There is a structure with a reflector attached. Since such a liquid crystal display device uses a flexible film substrate, it can be curved as a whole.

ある。However, in such a conventional liquid crystal display device, since a supporting member having rigidity is required, not only the number of parts is increased, but also the entire device becomes thicker and heavier. There was a problem. Further, when the liquid crystal display device is a transmissive type, a transparent supporting member is used, but even if the material of the supporting member is highly transparent glass, not only the transmittance is lowered but also the glass is used. In this case, there is a problem that the bending process is difficult and expensive. An object of the present invention is to provide a liquid crystal display device and a method for manufacturing the same, which can be curved as a whole.

(A) shows a normal flat plate type liquid crystal display device, and (B) shows a curved liquid crystal display device. It is a thing. First, as shown in FIG. 1A, a normal flat liquid crystal display device has a liquid crystal cell 3 in which a liquid crystal (not shown) is sealed between two film substrates 1 and 2 which are bonded together.
The structure is such that the polarizing plate 4 is attached to the front surface of the liquid crystal cell and the reflection plate 5 with the polarizing film is attached to the back surface of the liquid crystal cell 3.
In this case, the film substrates 1 and 2 made of polyether sulfone each have a thickness of about 100 μm. The thickness of both the polarizing plate 4 and the reflection plate with a polarizing film 5 is about 120 μm, and the size is about 110 × 20 mm. Further, the absorption axis of the polarizing plate 4 is orthogonal to the longitudinal direction of the liquid crystal cell 3 (direction along a predetermined side) as indicated by the solid arrow in FIG. On the other hand, the absorption axis of the polarizing plate-attached reflector 5 is in the same direction as the longitudinal direction of the liquid crystal cell 3, as indicated by the dotted arrow.

ることになる。Although not shown in the figure, a thermostatic chamber in which the temperature and humidity can be adjusted is prepared, and the thermostatic chamber shown in FIG.
Insert the flat liquid crystal display device shown in FIG.
When taken out after being left for a certain period of time at a temperature of about 90 ° C. and a humidity of about 90%, as shown in FIG. 1 (B), the polarizing film 4 has a convex surface along the longitudinal direction of the liquid crystal cell 3 and a polarizing film 4 side. A liquid crystal display device was obtained which was curved so that the plate 5 side was concave. The reason for curving in this manner is that the polarizing plate 4 and the reflecting plate with a polarizing film 5 have the property of curving along their respective absorption axes under the influence of temperature and humidity.
Further, the sizes of the polarizing plate 4 and the polarizing plate-attached reflecting plate 5 are both 1
Since the length is about 10 × 20 mm, the liquid crystal cell 3 is also slightly curved in the direction orthogonal to the longitudinal direction, but this curvature is hardly noticeable, and as a result, it is curved as described above.

4 hours, 48 hours, 72 hours, 96 hours, and 240 hours, the degree of curvature of the liquid crystal display device at each standing time (see FIG.
(Distance indicated by symbol Y in (B)) was taken out of the thermostat and measured 30 minutes later, and the results shown in Table 1 below were obtained.
【表１】[Table 1]

ことができることになる。As is clear from Table 1, the degree of curvature Y of the liquid crystal display device increases as the standing time becomes longer, but becomes saturated when the standing time exceeds a certain standing time (for example, 72 hours). Therefore, the bending degree Y of the liquid crystal display device is adjusted to the maximum bending degree (Y = 2.
It can be adjusted within the range of 3 cm). Further, since it is hardly returned to the original shape once it is bent, it is possible to obtain a liquid crystal display device which is itself bent as a whole. Even when a polarizing plate is used instead of the polarizing plate-attached reflection plate 5, it is possible to obtain a liquid crystal display device which is itself curved as a whole. As a result, the conventional supporting member having rigidity is not needed, and the problem resulting from this can be solved.

曲した液晶表示装置が得られた。In the above-mentioned embodiment, the curved surface is curved as shown in FIG. 1B. However, the absorption axis of the polarizing plate 4 is set in the same direction as the longitudinal direction of the liquid crystal cell 3, and the reflection plate 5 with the polarizing film is formed. When the absorption axis is orthogonal to the longitudinal direction of the liquid crystal cell 3, the liquid crystal cell 3 is curved in a direction opposite to the curved state shown in FIG. A liquid crystal display device was obtained which was curved so that the plate 4 side was concave and the polarizing film-attached reflection plate 5 side was convex.

ことができる。In the above embodiment, the polarizing plate 4 is attached to the front surface of the liquid crystal cell 3 and the reflection plate with a polarizing film 5 (or polarizing plate) is attached to the back surface of the liquid crystal cell 3 so as to be curved. However, the present invention is not limited to this. For example, only the back surface of the liquid crystal cell 3 has the polarizing plate-attached reflector 5
(Or a polarizing plate) may be attached to bend the curved surface, and then the polarizing plate 4 may be attached to the surface of the liquid crystal cell 3. In this case, it is possible to prevent the liquid crystal cell 3 from being bent at all in the direction orthogonal to the longitudinal direction. As a result, even when the shape of the liquid crystal cell is close to a square, it is possible to obtain a liquid crystal display device curved in an arbitrary direction by selecting the direction of the absorption axis of the polarizing plate or the like.

Further, in the above embodiment, the liquid crystal display device is heated and humidified to bend it, but only one of them may be used. That is, this is because the polarizing plate 4 and the polarizing plate-attached reflecting plate 5 have a property of curving even when only heated or only humidified.
