Abstract
In a display device using a substrate having flexibility, a drop in reliability due to defects such as cracks in the case where a substrate is made to curve is controlled. A display device is provided including a first substrate having flexibility, the first substrate including a curved part, an organic film covering a first surface of the first substrate and a second surface opposing the first surface in the curved part; and a pixel part and a drive circuit part arranged on the first surface.
Claims5
A semiconductor device comprising:
- a flexible substrate having a first surface and a second surface opposite side of the first surface;
- an active area on the first surface of the substrate, the active area includes a plurality of organic diode elements;
- a terminal part on the first surface of the substrate;
- a resin film covering the active area;
- and
- a support member on the second surface of the substrate, wherein
- the flexible substrate includes a curved part between the active area and the terminal part,
- an organic film covers the first surface of the substrate at the curved part,
- the resin film has an edge at the curved part side,
- the organic film is in contact with the edge of the resin film at the curved part side,
- the organic film does not overlap with the active area,
- a first part of the support member has an edge, and
- the edge of the resin film is between the active area and the edge of the first part of the support member in a planar view.
