And if it is possible in implementation, the features of different embodiments can be applied interactively.

Unless otherwise defined, all words (including technical and scientific terms) used herein have their usual meanings, and their meanings can be understood by those familiar with the field. Furthermore, the definitions of the above-mentioned words in commonly used dictionaries should be interpreted as meaning consistent with the relevant fields of the present invention in the content of this specification. Unless specifically defined, these terms will not be interpreted as idealized or overly formal.

Please refer to Figures 1-2. FIG. 1 is a partial top view of a display 100 according to an embodiment of the present invention, in which the first body 121 of the first adhesive material 120 is omitted. Figure 2 is a cross-sectional view taken along line A-A in Figure 1. For example, the display 100 may be a flexible liquid crystal display (LCD) or a flexible organic light-emitting diode (OLED), but the invention is not limited thereto. In order to make it easier to understand the present invention, this specification and related figures The liquid crystal, light-emitting diode, and sealant of the display 100 are omitted.

In this embodiment, as shown in FIGS. 1 to 2, a display 100 includes a flexible substrate 110, a first adhesive material 120, a color filter 130, an upper polarizer 140, and a lower polarizer 145. The flexible substrate 110 has a first surface 111 and a second surface 112 opposite to each other. The first surface 111 has a connected first zone Z1 and a second zone Z2. The first zone Z1 is actually the display area of the display 100, and the The second area Z2 is the non-display area of the display 100. The flexible substrate 110 further has a plurality of first grooves G1. The first grooves G1 are provided in the second area Z2 of the first surface 111, and the first grooves G1 extend along the The first direction D1 is arranged and respectively extends along the second direction D2. The second direction D2 is substantially perpendicular to the first direction D1 and perpendicular to the connecting direction of the first zone Z1 and the second zone Z2. In the first groove G1 At least one of the first grooves G1 has a first depth P1, at least another of the first grooves G1 has a second depth P2, and the first depth P1 and the second depth P2 are different from each other. The first adhesive material 120 includes a first main body 121 and a plurality of first protrusions 122. The first main body 121 covers the second area Z2 of the first surface 111. The first protrusions 122 are connected to the first main body 121 and fill the first A groove G1. The color filter 130 is stacked on the first area Z1 of the first surface 111. The upper polarizer 140 is stacked on the color filter 130. The lower polarizer 145 is stacked on the second surface 112 of the flexible substrate 110 and faces away from the first zone Z1.

It should be noted that the first adhesive material 120 is harder than the flexible substrate 110. In other words, the Young's Modulus of the first adhesive material 120 is greater than the Young's Modulus of the flexible substrate 110. In this way, even if internal cracks are generated in the flexible substrate 110 during the manufacturing process, the first protrusion 122 of the first adhesive material 120 will not allow the internal cracks to pass through, thus effectively preventing the internal cracks. The expansion of the trace causes further damage to the flexible substrate 110, so as to extend the service life of the flexible substrate 110. Moreover, the first groove G1 is provided on the flexible substrate 110 to accommodate the first protrusion 122 to achieve a balance between support and stress without reducing the flexibility of the flexible substrate 110, in other words In other words, the flexibility of the flexible substrate 110 itself can be maintained.

Furthermore, the user can judge the magnitude and distribution of the stress at different positions according to the stress of the flexible substrate 110, thereby adjusting the depth of the first groove G1, that is, the length of the first protrusion 122. For example, as shown in Figure 2, the first depth P1 in the first groove G1 and the second depth P2 in the first groove G1 are different from each other, and the farther away the first depth P1 is from the first zone Z1 The depth of the groove G1 is also shallower, that is, the length of the first protrusion 122 is shorter, but the present invention is not limited to this.

Furthermore, FIG. 6 further shows a plurality of metal traces 200 and a plurality of bonding pads 250. In practical applications, the metal trace 200 and the bonding pad 250 are both disposed on the flexible substrate 110, and the metal trace 200 is electrically connected between the first zone Z1 and the bonding pad 250. As described above, even if internal cracks occur in the flexible substrate 110 during the manufacturing process, since the first protrusion 122 of the first adhesive material 120 will not let the internal cracks pass, it can effectively prevent the internal cracks. The expansion of the trace causes further damage to the flexible substrate 110, and the flexible substrate 110 is effectively protected. In this way, when the flexible substrate 110 is bent, the flexible substrate 110 is not easily damaged due to the protection of the first protrusion 122, so that the metal trace 200 is not easy to be damaged when the flexible substrate 110 is bent. damage. To simplify the drawings, the metal traces 200 and bonding pads 250 are no longer shown in other drawings.

In summary, the technical solutions disclosed in the foregoing embodiments of the present invention have at least the following advantages:

(1) Since the first rubber material is harder than the flexible substrate, even if the flexible substrate produces internal cracks during the manufacturing process, the first protrusion of the first rubber material will not let the internal cracks pass through, so it can be effective Prevent the expansion of internal cracks and cause further damage to the flexible substrate, so as to extend the service life of the flexible substrate. Moreover, the method of providing the first groove on the flexible substrate to accommodate the first protrusion does not reduce the flexibility of the flexible substrate. In other words, the flexibility of the flexible substrate itself can be maintained .

(2) Since the first protrusion corresponding to the first groove and the first protrusion corresponding to the second groove can extend in a zigzag path or a shape path, the first protrusion and the flexible substrate The contact area can be effectively increased, so that the force of the first protrusion and the flexible substrate to adhere to each other can also be effectively increased, so that the connection between each other can be more stable, which helps to strengthen the integration of the flexible substrate and the first adhesive material strength.

(3) By filling the first gap between the first step structure and the upper polarizer by the first extension portion of the first adhesive material, the strength of the connection between the first adhesive material and the color filter is effectively strengthened, thereby enhancing the display The overall strength.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone familiar with the art can make various changes and modifications without departing from the spirit and scope of the present invention.
