Abstract
Provided is a display device having a flexible substrate including an active region and a wiring region. The active region possesses a plurality of pixels each including a display element. The wiring region has a plurality of terminals, and a plurality of wirings extends from the active region to the plurality of terminals. An insulating film included in the active region and extending from the active region has a sidewall between an edge of the flexible substrate and the wiring adjacent to the edge in the wiring region. The sidewall has a curved portion on a plane in which the plurality of wirings is arranged, and a distance between the edge and the curved portion is curvedly varied.
Claims18
A display device comprising:
- a flexible substrate including:
- an active region comprising a plurality of pixels each including a display element;
- and
- a wiring region comprising:
- a plurality of terminals;
- and
- a plurality of wirings extending from the active region to the plurality of terminals,
- wherein, in the wiring region, an insulating film included in the active region and extending from the active region has a sidewall between an edge of the flexible substrate and the wiring adjacent to the edge,
- the sidewall has a curved portion on a plane in which the plurality of wirings is arranged, and
- a distance between the edge and the curved portion curvedly varies.
A display device comprising:
- a flexible substrate including an active region and a wiring region,
- wherein the active region comprises:
- an undercoat over the flexible substrate;
- a semiconductor film, a gate, and a gate insulating film sandwiched by the semiconductor film and the gate over the undercoat;
- an interlayer film over the semiconductor film, the gate, and the gate insulating film;
- and
- a source and a drain electrically connected to the semiconductor film,
- the wiring region comprises:
- a terminal over the flexible substrate;
- and
- a wiring located over the flexible substrate and
- electrically connecting the active region to the terminal,
- a sidewall of at least one of the undercoat, the gate insulating film, and the interlayer film is located between an edge of the flexible substrate and the wiring in the wiring region,
- the sidewall has a curved portion on a plane in which the wiring is arranged, and
- a distance between the edge and the curved portion curvedly varies.
