Patent attributes
A display device includes a display panel and a flexible substrate. A first pad and a second pad are arranged on the display panel. The flexible substrate includes a first layer, a first insulating layer, and a second layer on a bending area. A first metal line is arranged in the first layer and connected to the first pad. A second metal line is arranged in the second layer and connected to the second pad. A straightened length of the first metal line is greater than that of the second metal line. The design of a double-layer metal line effectively improves the stress intensity of the metal line in the outer bending area. Therefore, the inner and outer double-line metal line in the bending area is balanced by force, so that the stability of the inner and outer double-line metal line is relatively uniform.
