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 first substrate;

pixels in a display area;

signal lines arrayed in a first direction;

scanning lines arrayed in a second direction;

a first circuit element, on the first substrate, located outside the display area;

a second circuit element, on the first substrate, located outside the display area;

a third circuit element, on the first substrate, located outside the display area; and

a fourth circuit element, on the first substrate, located outside the display area,

wherein

the first substrate has a shape including a curved portion at least in a part of an outline,

the signal lines include a first signal line,

the first circuit element is connected to the first signal line,

the second circuit element is connected to the first signal line through the first circuit element and is not directly connected to any other signal lines,

the first circuit element is shifted obliquely from the second circuit element with respect to the first direction and the second direction,

the first circuit element is connected to the second circuit element by a first conductive line,

the scanning lines include a first scanning line,

the third circuit element is connected to the first scanning line,

the fourth circuit element is connected to the first scanning line through the third circuit element and is not directly connected to any other scanning lines,

the third circuit element is shifted obliquely from the fourth circuit element with respect to the first direction and the second direction,

the third circuit element is connected to the fourth circuit element by a second conductive line,

the first circuit element, the second circuit element, the third circuit element, and the fourth circuit element are located between the outline of the first substrate and the display area at the curved portion,

the first circuit element is located between the second circuit element and the display area at the curved portion, and

the second circuit element is located between the outline of the first substrate and the first circuit element at the curved portion.

2. The display device of claim 1 , wherein the second conductive line extends obliquely with respect to the first direction and the second direction.

3. The display device of claim 1 , wherein the first conductive line extends obliquely with respect to the first direction and the second direction.

4. The display device of claim 2 , wherein the first conductive line extends obliquely with respect to the first direction and the second direction.

5. The display device of claim 4 , wherein

the third circuit element is a shift register circuit, and

the fourth circuit element is a buffer circuit.

6. The display device of claim 1 , wherein

a part of the first circuit element faces the fourth circuit element in the first direction, and

a part of the second circuit element faces the first circuit element in the second direction.

7. The display device of claim 1 , wherein

a part of the first circuit element faces the fourth circuit element in the second direction, and

a part of the second circuit element faces the first circuit element in the second direction.
