Abstract

A display device includes a base film including a first region and a plurality of second regions having the first region therebetween; an inorganic insulating film on the base film, the inorganic insulating film being in contact with the plurality of second regions of the base film; a plurality of first pixels overlapping the first region; and a plurality of second pixels overlapping the plurality of second regions with the inorganic insulating film being between the plurality of second pixels and the plurality of second regions. The inorganic insulating film is divided by the first region and is discontinuous between the plurality of second regions.

Claims (45)

1. A display device comprising:

a base film including a first region and a plurality of second regions having the first region therebetween;

an inorganic insulating film on the base film, the inorganic insulating film being in contact with the plurality of second regions of the base film;

a plurality of first pixels overlapping the first region; and

a plurality of second pixels overlapping the plurality of second regions with the inorganic insulating film being between the plurality of second pixels and the plurality of second regions,

wherein

the inorganic insulating film is divided by the first region and is discontinuous between the plurality of second regions, and

the first region of the base film is configured to be bent.

2. The display device according to claim 1 , wherein

the plurality of first pixels and the plurality of second pixels each include:

a semiconductor film and a gate electrode overlapping each other; and

a gate insulating film between the semiconductor film and the gate electrode, and

the inorganic insulating film is between the base film and the gate insulating film in the plurality of second regions.

3. The display device according to claim 1 , wherein

the base film is flexible.

4. The display device according to claim 1 , wherein the

base film contains a polyimide.

5. The display device according to claim 2 , wherein

the gate insulating film is in direct contact with the base film in the first region.

6. The display device according to claim 1 , further comprising a wiring extending from one of the plurality of second regions to the first region, wherein

on the first region, the wiring includes a portion wider than a portion of the wiring on the second region.

7. The display device according to claim 1 , further comprising a wiring extending from one of the plurality of second regions to the first region, wherein

the wiring includes:

a first portion extending in a first direction;

a second portion extending in a second direction from an end of the first portion, the second direction being different from the first direction; and

a third portion extending in the first direction from an end of the second portion opposite to the first portion, and

at least a part of the first portion is on one of the plurality of second regions, and the third portion is on the first region.

8. A display device comprising:

a base film having a first display region including a plurality of first pixels, a second display region including a plurality of second pixels, and a first region between the first display region and the second display region; and

an inorganic insulating film overlapping the base film in the first display region and the second display region, wherein

the first region of the base film is exposed from the inorganic insulating film, and

the first region of the base film is configured to be bent.

9. The display device according to claim 8 , wherein

the plurality of first pixels and the plurality of second pixels each include:

a semiconductor film and a gate electrode overlapping each other; and

a gate insulating film between the semiconductor film and the gate electrode, and

the gate insulating film is shared by the plurality of first pixels and the plurality of second pixels and is in contact with the base film in the first region.

10. The display device according to claim 8 , wherein

the base film is flexible.

11. The display device according to claim 8 , further comprising a wiring extending from the first display region to the first region, wherein

in the first region, the wiring includes a portion wider than in a portion of the wiring on the first display region.

12. The display device according to claim 8 , wherein

the base film has a first side extending in the first display region, the first region and the second display region, and a second side facing the first side;

the first region is continuous from the first side to the second side; and

the wiring is not in the first region.
