SUMMARY

Technical Problem

A flexible display device (hereinafter simply referred to as “display device”) is cut by laser light, and such cutting tends to generate a crack at a cutting surface. The generated crack propagates inside the display device with the passage of time when the sectional surface is exposed to the outside air. If oxygen or moisture penetrates into the display device through the crack, there is a concern that display defects may occur. When the cutting surface is exposed to outside air, the generated crack develops inside the display device with the passage of time. There is a concern that entry of oxygen or moisture into the display device through the crack may cause a display defect.

Solution to Problem

A display device in accordance with an aspect of the present disclosure is a display device including a display area and a frame region which is a non-display area provided outside the display area, wherein in the frame region, at least a flexible substrate and a moisture-proof layer are disposed in this order, and a metal oxide film is further provided between the flexible substrate and the moisture-proof layer.

A method for manufacturing a display device in accordance with an aspect of the present disclosure is a method for manufacturing a display device including a display area and a frame region which is a non-display area provided outside the display area, the method including the steps of: in the frame region, disposing at least a flexible substrate and a moisture-proof layer in this order, and further providing a metal oxide film between the flexible substrate and the moisture-proof layer; and cutting off an unnecessary part from the display device at a cutting surface of the frame region by use of laser light.

Advantageous Effects of Invention

According to an aspect of the present disclosure, it is possible to protect a flexible substrate and prevent the generation of a crack and the development of a crack inside a display device.
