Abstract

According to one embodiment, a display device includes a driver, a pixel circuit disposed to be apart from the driver in a plan view and to be electrically connected to the driver, a first pixel electrode disposed to overlap the pixel circuit in a plan view and to be electrically connected to the pixel circuit, a second pixel electrode disposed to overlap the driver in a plan view and to be closer to an outer edge of a display area than the first pixel electrode, and a relay line disposed between the pixel circuit and the first pixel electrode and between the driver and the second pixel electrode, the relay line electrically connecting the first pixel electrode and the second pixel electrode.

Claims (38)

1. A display device comprising:

a driver;

pixel circuits disposed to be apart from the driver in a plan view and to be electrically connected to the driver;

a first pixel electrode disposed to overlap one of the pixel circuit in a plan view and to be electrically connected to the pixel circuit;

a second pixel electrode disposed so as not to overlap any of those pixel circuits in a plan view, and a distance between the second pixel electrode and an outer edge of a display area is smaller than a distance between the first pixel electrode and the outer edge of a display area;

a connecting line disposed between the pixel circuit and the first pixel electrode and between the driver and the second pixel electrode, the connecting line electrically connecting the first pixel electrode and the second pixel electrode;

a light shield disposed to overlap at least a part of the first pixel electrode in a plan view,

wherein the display device is a reflective liquid crystal display device, and

the first pixel electrode is disposed between the driver and the light shield in a plan view.

2. The display device according to claim 1 , further comprising:

a first insulating film disposed between the driver and the connecting line and between the pixel circuit and the connecting line;

a second insulating film disposed between the connecting line and the first pixel electrode and between the connecting line and the second pixel electrode;
