Abstract

Claims (39)

1 . A display device comprising:

a substrate comprising a front portion, a first side portion extending from a first side of the front portion, a second side portion extending from a second side of the front portion, and a corner portion between the first side portion and the second side portion and having a cutout pattern;

a first display area comprising first pixels in the front portion; and

a second display area comprising second pixels and dummy pixel drivers in the cutout pattern of the corner portion,

wherein each of the second pixels comprises a subpixel light-emitting unit for emitting light and a subpixel driver connected to the subpixel light-emitting unit, and

wherein any one of the dummy pixel drivers is closer to an edge of the cutout pattern than the subpixel driver of any one of the second pixels is to the edge of the cutout pattern, such that the any one of the dummy pixel drivers is between the subpixel driver of the any one of the second pixels and the first display area in plan view.

2 . The display device of claim 1 , wherein the second display area comprises a driving area in which the subpixel drivers of the second pixels are located and a dummy area in which the dummy pixel drivers are located,

wherein the dummy area surrounds the driving area.

3 . The display device of claim 1 , further comprising a connection line connecting the subpixel light-emitting unit and the subpixel driver.

4 . The display device of claim 3 , wherein the connection line overlaps one or more of the dummy pixel drivers.

5 . The display device of claim 1 , wherein each of the dummy pixel drivers comprises:

a driving transistor;

a first transistor connected to a first electrode of the driving transistor;

a second transistor between a gate electrode and a second electrode of the driving transistor;

a third transistor between the gate electrode of the driving transistor and an initialization voltage line to which an initialization voltage is applied;

a fourth transistor between the second electrode of the driving transistor and the initialization voltage line; and

a fifth transistor between the first electrode of the driving transistor and a first power line to which a first power supply voltage is applied.

6 . The display device of claim 5 , wherein at least one of a gate electrode of the first transistor, a gate electrode of the second transistor, a gate electrode of the third transistor, a gate electrode of the fourth transistor, and a gate electrode of the fifth transistor is connected to the first power line.

7 . The display device of claim 5 , wherein the gate electrode of the first transistor, the gate electrode of the second transistor, the gate electrode of the third transistor, the gate electrode of the fourth transistor, and the gate electrode of the fifth transistor are connected to the first power line.

8 . The display device of claim 7 , wherein a first electrode of the first transistor is connected to a data line to which a data voltage is applied.

9 . The display device of claim 5 , wherein the first electrode of the first transistor is connected to a dummy data line to which no voltage is applied.

10 . The display device of claim 9 , wherein the first electrode of the first transistor is connected to the first power line.

11 . The display device of claim 1 , wherein a length of the subpixel driver in one direction is the same as a length of any one of the dummy pixel drivers in the one direction.

12 . The display device of claim 11 , wherein a length of the subpixel driver in another direction is the same as a length of any one of the dummy pixel drivers in the other direction, and

wherein the other direction is orthogonal to the one direction.

13 . A display device comprising:

a substrate comprising a front portion, a first side portion extending from a first side of the front portion, a second side portion extending from a second side of the front portion, and a corner portion between the first side portion and the second side portion and having a cutout pattern;

a first display area comprising first pixels in the front portion; and

a second display area comprising second pixels and dummy pixel drivers in the cutout pattern of the corner portion,

wherein each of the second pixels comprises a subpixel light-emitting unit for emitting light and a subpixel driver connected to the subpixel light-emitting unit, and

wherein any one of the dummy pixel drivers is closer to an edge of the cutout pattern than the subpixel driver of any one of the second pixels is to the edge of the cutout pattern, and

wherein the dummy pixel drivers overlap the subpixel light-emitting unit.

14 . A display device comprising:

a substrate comprising a front portion, a first side portion extending from a first side of the front portion, a second side portion extending from a second side of the front portion, and a corner portion between the first side portion and the second side portion and having a cutout pattern;

a first display area comprising first pixels in the front portion; and

a second display area comprising second pixels and dummy pixel drivers in the cutout pattern of the corner portion,

wherein each of the second pixels comprises a subpixel light-emitting unit for emitting light and a subpixel driver connected to the subpixel light-emitting unit, and

wherein any one of the dummy pixel drivers is closer to an edge of the cutout pattern than the subpixel driver of any one of the second pixels is to the edge of the cutout pattern, and

wherein an area of the subpixel driver is the same as an area of any one of the dummy pixel drivers.
