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 (34)

1 . A display device comprising:

a first substrate;

pixels in a display area;

first lines arrayed in a first direction;

second lines arrayed in a second direction; and

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

wherein

the display area has a shape including a stepped portion at least in a part of an outline of the display area,

the first lines include a first conductive line,

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

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

the first circuit element includes a shift register circuit configured to supply an output voltage to the second circuit element via the second conductive line,

the second circuit element includes a buffer circuit configured to supply a signal to the first conductive line in accordance with the output voltage from the first circuit element,

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

the second circuit element is located between the first circuit element and the display area at the stepped portion.

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

4 . A display device comprising:

a first substrate;

pixels in a display area;

first lines arrayed in a first direction;

second lines arrayed in a second direction; and

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

wherein

the display area has a shape including a stepped portion at least in a part of an outline of the display area,

the first lines include a first conductive line,

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

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

the first circuit element includes a shift register circuit configured to supply an output voltage to the second circuit element via the second conductive line,

the second circuit element includes a buffer circuit configured to supply a signal to the first conductive line in accordance with the output voltage from the first circuit element,

a line segment connecting a center of the first circuit element in the second direction and a center of the second circuit element in the second direction is not parallel to the first direction, and

the second circuit element is located between the first circuit element and the display area at the stepped portion.

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

6 . The display device of claim 4 , wherein the first circuit element is located between the outline of the first substrate and the second circuit element at the stepped portion.
