Abstract

According to one embodiment, a display device includes a pair of substrates including a display area in which pixels are arranged, pixel electrodes and memories provided in the pixels, signal lines supplied with digital signals, switching elements connecting the memories and the signal lines, scanning lines supplied with scanning signals, a first driver unit, and a second driver unit. The first driver unit is provided in a peripheral area around the display area, and supplies the digital signal to the signal line. The second driver unit is provided in the peripheral area, and supplies the scanning signal to the scanning line. In the display device, at least a part of the first driver unit is provided between the display area and the second driver unit.

Claims (36)

1. A display device comprising:

a substrate;

video signal lines arrayed in a first direction, in a display area;

scanning lines arrayed in a second direction intersecting with the first direction, in the display area;

a driver unit provided outside of the display area and connected to the scanning lines; and

an integrated circuit mounted on the substrate;

wherein

an outer shape of the substrate includes a first arc-edge and a second arc-edge,

the second arc-edge opposes to the first arc-edge in the second direction,

a first part of the driver unit is formed along the first arc-edge,

a second part of the driver unit is formed along the second arc-edge,

the scanning lines include a first scanning line and a second scanning line,

the video signal lines include a first video signal line intersecting with the first and second scanning lines,

the first part of the driver unit includes a first circuit connected to the first scanning line,

the second part of the driver unit includes a second circuit connected to the second scanning line,

a first distance is a distance between the first video signal line and the first circuit in the first direction,

a second distance is a distance between the first video signal line and the second circuit in the first direction,

the first distance is larger than the second distance, and

the integrated circuit is located closer to the first arc-edge than the second arc-edge.

2. The display device of claim 1 , wherein

a third distance is a distance between the first circuit and the first arc-edge, in a normal direction of the first arc-edge,

a fourth distance is a distance between the second circuit and the second arc-edge, in a normal direction of the second arc-edge, and

the third distance is less than the fourth distance.

3. The display device of claim 1 , further comprising:

a third circuit connected to the first video signal lines, wherein

the third circuit is located between the first circuit and the display area, in the first direction.

4. The display device of claim 1 , further comprising:

a third circuit connected to one of the video signal lines except for the first video signal line,

the third circuit is located between the first circuit and the first video signal line, in the first direction.

5. The display device of claim 1 , wherein

the first circuit is an outermost circuit of the driver unit in a side of the second direction, and

the second circuit is an outermost circuit of the driver unit in another side of the second direction.

6. The display device of claim 1 , wherein

the driver unit includes a third part,

the third part is provided between the first part and the second part, and

the third part is formed in a straight shape.
