Abstract

A display device includes a first pixel formed by a red sub pixel, a green sub pixel, and a white sub pixel and a second pixel formed by a red sub pixel, a green sub pixel, and a blue sub pixel. The red sub pixel and the green sub pixel are arranged in a second direction. The white sub pixel is arranged adjacently to the red sub pixel and the green sub pixel in a first direction. The blue sub pixel is adjacently to the red sub pixel and the green sub pixel in the first direction. A light shielding wiring layer extending in the first direction is arranged between the red sub pixel and the green sub pixel of each of the first pixel and the second pixel.

Claims (28)

1. A display device comprising

an array substrate,

an opposite substrate, and

a liquid crystal layer sandwiched by the array substrate and the opposite substrate, wherein

the array substrate includes

a first pixel formed by a red sub pixel, a green sub pixel, and a white sub pixel,

a second pixel formed by a red sub pixel, a green sub pixel, and a blue sub pixel,

a scanning line extending in a first direction,

a signal line extending in a second direction, and

first and second light shielding wiring layers,

the red sub pixel and the green sub pixel of the first pixel are arranged in the second direction,

the white sub pixel of the first pixel is arranged adjacently to the red sub pixel and the green sub pixel in the first direction,

the red sub pixel and the green sub pixel of the second pixel are arranged in the second direction,

the blue sub pixel of the second pixel is arranged adjacently to the red sub pixel and the green sub pixel in the first direction,

the first light shielding wiring layer is arranged between the red sub pixel and the green sub pixel of the first pixel in a way of extending in the first direction, and

the second light shielding wiring layer is arranged between the red sub pixel and the green sub pixel of the second pixel in a way of extending in the first direction,

wherein the scanning line includes first, second, and third scanning lines,

the first scanning line is connected to the red sub pixel and the white sub pixel of the first pixel,

the second scanning line is connected to the green sub pixel of the first pixel and the red sub pixel and blue sub pixel of the second pixel, and

the third scanning line is connected to the green sub pixel of the second sub pixel.

2. The display device according to claim 1 ,

wherein the signal line includes first, second, and third signal lines,

the first signal line is connected to the red sub pixels of the first and the second pixels,

the second signal line is connected to the green sub pixels of the first and the second pixels, and

the third signal line is connected to the white sub pixel of the first pixel and the blue sub pixel of the second pixel.

3. The display device according to claim 2 , wherein

the red sub pixel and the green sub pixel of the first pixel and the red sub pixel and the green sub pixel of the second pixel are arranged between the first signal line and the second signal line, and

the third signal line is arranged between the second signal line and the white sub pixel of the first pixel and the blue sub pixel of the second pixel.
