Display device and method of manufacturing the same
There is provided a display device including a flexible substrate having a first surface and a second surface opposite to the first surface, the substrate including a display region on the first surface and a bending region on a part of the first surface or on a part of the second surface, the display region being arranged with a plurality of pixels, the bending region including an uneven pattern alternately arranged with regions, the thickness of the substrate being different in each region; and a plurality of wirings transmitting a signal for driving the plurality of pixels, each of the plurality of wirings being arranged in a top part or a bottom part of a convex portion in the uneven pattern in the bending region.
1. A method of manufacturing a display device, comprising:
forming a plurality of wirings on a first surface of a flexible substrate, the substrate having the first surface and a second surface opposite to the first surface and including a first region and a second region, each of the plurality of wirings transmitting a signal for driving a plurality of pixels arranged in the first region; and
forming an uneven pattern in the substrate by etching regions respectively corresponding to areas among the plurality of wirings from a side of the first surface or a side of the second surface in the second region,
wherein each of the plurality of wirings is arranged to bend or meander in the second region.
2. The method of manufacturing the display device according to claim 1 , further comprising
folding the second region.
3. The method of manufacturing the display device according to claim 2 , wherein
the substrate includes a third region where a terminal is arranged,
the second region is arranged between the first region and the third region, and
the first region and the third region overlap each other when the second region is folded.
4. The method of manufacturing the display device according to claim 1 , further comprising
forming an insulating layer on the first surface of the substrate before forming the plurality of wirings.
5. The method of manufacturing the display device according to claim 4 , further comprising
removing the insulating layer in the second region before forming the plurality of wirings.
6. The method of manufacturing the display device according to claim 1 , wherein
a convex portion in the uneven pattern has a tapered shape.
