Display device
First Claim
1. A display device comprising a pixel defined by a plurality of sub pixels, wherein:
- the plurality of sub pixels are a red sub pixel to display red, a green sub pixel to display green, a blue sub pixel to display blue, and a yellow sub pixel to display yellow; and
when an input signal corresponding to green of an sRGB color space is externally input from outside the display device, an image is provided on the display device by the green sub pixel and the yellow sub pixel;
whereinan increase in ratios of gray scale levels of the green sub pixel and the yellow sub pixel with respect to an increase of the gray scale level of the input signal is different between a first range of the gray scale level of the input signal from a minimum level to a prescribed intermediate level and a second range of the gray scale level of the input signal from the prescribed intermediate level to a maximum level.

Abstract
A display device (100) according to the present invention includes a pixel defined by a plurality of sub pixels. The plurality of sub pixels are a red sub pixel (R) to display red, a green sub pixel (G) to display green, a blue sub pixel (B) to display blue, and a yellow sub pixel (Ye) to display yellow. When an input signal corresponding to green of the sRGB color space is externally input, the display device (100) according to the present invention provides display by use of the green sub pixel (G) and also the yellow sub pixel (Ye). According to the present invention, a multiple primary color display device which suppresses decline of the display quality when an input signal corresponding to green of the sRGB color space is externally input is provided.
