The semiconductor device 100 has a display portion 101 . The display unit 101 can be folded. The semiconductor device 100 has a first housing 111 holding a display portion 101 and a second housing 112 . Since the display unit 101 is folded, the first housing 111 is
can be in contact with the housing 112 of the In order to maintain the folded form, the first housing 1
11 and the second housing, the first housing 111 has a first fitting portion 113, and the second housing 112 has a second fitting portion. 114. In a second region 122 where the first housing 111 and the second housing are in contact with each other, the first housing 111 has a third fitting portion 123, and the second housing 112 It has a fourth fitting portion 124 . For example, the first
The fitting portion 113 and the second fitting portion 114 can be configured by a hook portion having a claw portion such as a side release buckle or a front release buckle. The third fitting portion 123 and the fourth
The fitting portion 124 can be composed of a side release buckle, a front release buckle, or the like. In this case, the first fitting portion 113 or the third fitting portion 123 is a socket (claw concave portion), and the second fitting portion 114 or the fourth fitting portion 124 is a plug (claw convex portion). should be

The display 101 can also be used in a folded configuration. Therefore, the display unit 1
Fold so that part of 01 faces the front. In this state, the first housing 111 and the display unit 101 are connected.
The first housing 111 has a transparent region 111a in a region 118 where the . The display unit 101 can be in contact with the transparent region 111a. The transparent region 111a is the display section 101
may not be present on the entire surface, and may have the shape of a frame.

In order to turn a part of the display unit 101 upside down, for example, the display unit 101 may have an even number of bending regions and be folded so that the bending directions of the bending regions are reversed. Figure 1(A)
2 shows a form in which there are two bending areas (128, 129) and a part of the display section 101 is facing forward. The region 128 is folded in the opposite direction to the region 129, that is, if the region 128 is a mountain fold, the region 129 will be a valley fold. In the bending area, if the display unit 101 is an active type panel, the radius of curvature is preferably 4 mm or more in consideration of the bending strength of the transistor. Of course, the flexible display unit 101 can have a curved surface other than the folded area.

An internal thickness 119 of the semiconductor device 100 formed by the first housing 111 and the second housing 112 is two to five times the radius of curvature of the display section 101 . The first housing 111 and the second housing 112 may have curved surfaces matching the curvature of the display unit 101 . Thereby, the first
The space between the first housing 111 or the second housing 112 and the display unit 101 can be reduced. As a result, the thickness 120 of the semiconductor device 100 can be made even thinner. This thickness 120 is preferably two times or less the internal thickness 119 in consideration of the sophistication of the design.

FIG. 1B shows how the display portion 101 is unfolded from the folded state. The first fitting portion 113 to the fourth fitting portion 124 are brought into a non-fitting state, and the first housing 111 is separated from the second housing 112 . A part of the display unit 101 is fixed to a region including the transparent region 111 a of the first housing 111 , and the other part of the display unit 101 is fixed to a part of the second housing 112 .

2A and 2B show a state in which the display section 101 is spread. FIG. 2A is a cross-sectional view, and FIG. 2B is a top view. As shown in FIGS. 2A and 2B, the display portion 101 has a region 146 overlapping with the first housing 111, a region 148 overlapping with the second housing 112, and a region 147 overlapping neither. Since the region 147 does not contact any housing, the region 146,
Compared to 148, it is more flexible. Region 147 can have a larger area than region 146 . Region 147 can have a larger area than region 148 .

A region 146 becomes a displayable region when the display unit 101 is folded as shown in FIG. As such, region 146 can have a larger area than region 148 .

If the visibility of the display unit 101 is to be made equal between the areas 146 to 148, as shown in FIG.

A black film 145 is placed on the . The film 145 has an organic material, and the display section 101
Use a film thinner than As a result, it is possible to bend following the display unit 101 . The film 145 is preferably made of a high-strength, high-modulus material so that it can withstand repeated bending and stretching and twisting, because it also serves as a reinforcement. Based on these considerations, the film 145 may be made of, for example, super fibers such as aramid or polyarylate.

By having the first housing 111 and the second housing 112 as shown in FIG. 2B, the expanded display portion 101 can be used. Of course, the display unit 101 may be used while holding only the first housing 111 . Alternatively, the display portion 101 may be used by holding only the second housing 112 .

Since the first housing 111 serves as a handle, the hardness may be changed to make it easier to grip. A region 111b of the first housing 111 corresponding to the side surface of the semiconductor device 100 may have a harder material than other regions, while other regions may have a softer material. second housing 1
12, the region 112a corresponding to the side surface of the semiconductor device 100 may have a harder material than the other regions, while the other regions may have a softer material.

The first housing 111 may include an input device. The second housing 112 may include an input device.

When the third fitting portion 123 and the fourth fitting portion 124 overlap the display portion 101 and the visibility is lowered, the third fitting portion 123 and the fourth fitting portion 124 have translucency. It is good to have a material that has Further, as shown in FIG. 2B, these fitting portions are preferably arranged at the end portions of the display portion 101 in consideration of visibility, but they may be arranged up to the central portion of the display portion 101 . On the other hand, the first fitting portion 113 and the second fitting portion 114 may be of any type as long as they can fit and disconnect the housing 111 and the housing 112 .

If the region 112a corresponding to the side surface of the semiconductor device 100 from the fitting portion 114 is composed of a portion having translucency, the region where the display can be confirmed when the display portion 101 is folded becomes large, which is preferable. The display unit 101 corresponding to this area may be used to receive a simple signal (whether there is an e-mail or an incoming call) such as blinking/lighting of a lamp.

Also, if the display unit 101 is of a dual emission type, the first fitting unit 113
, the second fitting portion 114, and the portion of the housing 111 that is adhered to the display portion 101 are preferably translucent. In this case, the film 145 has translucency. Housing 111 and housing 112
may have translucency.

Fold region 129 is provided between regions 146 and 147 , and fold region 128 is provided between regions 147 and 148 .

In addition, a touch panel may be mounted as an input device that overlaps with the display unit 101 . Touch panels include optical touch panels, capacitive touch panels, and the like. An optical touch panel is preferable because the display unit 101 is highly flexible.

In this way a collapsible device can be provided.

As shown in FIG. 3 , a first cushioning material 131 may be arranged between the first housing 111 and the display section 101 . Similarly, the second cushioning material 132 is provided between the second housing 112 and the display unit 101
may be placed between The first housing 111 and the second housing 112 have a harder material than the display unit 101 in order to hold the display unit 101 . With the display unit 101 folded, when the first housing 111 and the display unit 101 and the second housing 112 and the display unit 101 come into contact,
The display unit 101 becomes susceptible to impact. Therefore, as shown in FIG. 3, the first cushioning material 13
The impact on the display unit 101 can be softened by the first and second cushioning materials 132 .

FIG. 4A shows a semiconductor device 100 having an external circuit region 150. FIG. The display portion 101 having a pixel portion may have a scanning line driver circuit and a signal line driver circuit on the same plane as the pixel portion. However, since the display portion 101 has the bent regions 128 and 129 , the scanning line driver circuit and the signal line driver circuit are preferably provided in the external circuit region 150 . That is, the external circuit area 150 is provided with a circuit section. As a result of providing the circuit section in the external circuit area 150, the flexibility of the display section 101 can be enhanced. The wiring of the display section 101 can be electrically connected to the driving circuit of the external circuit area 150 via a flexible printed circuit board (FPC, not shown). In order to maintain the miniaturization of the semiconductor device 100, the external circuit area 150 is
It is preferable to arrange so as to overlap with the display portion 101 . For example, it can be arranged outside the second housing 112 . A battery or the like may be arranged in the external circuit area 150 in addition to the drive circuit.

A) differs in the location of the external circuit area 150 . The external circuit area 150 a may be provided in contact with the first housing 111 and the external circuit area 150 b may be provided in contact with the second housing 112 . As shown in FIG. 4A, the thickness of the entire semiconductor device 100 can be reduced.
