Active matrix display device

A display device comprising:

• a pixel including four sub-pixels, the four sub-pixels including:
• a first sub-pixel including a first color filter that transmits light having a spectrum peak falling on a spectrum of reddish green;
• a second sub-pixel including a second color filter that transmits light having a spectrum peak falling on a spectrum of bluish green;
• a third sub-pixel including a third color filter that transmits light having a spectrum peak falling on a spectrum of red;
• and
• a fourth sub-pixel including a fourth color filter that transmits light having a spectrum peak falling on a spectrum of blue, wherein
• the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel each include a reflective electrode that reflects light transmitted through the corresponding color filter,
• a side of the first sub-pixel is directly adjacent to a side of the second sub-pixel,
• each of the third sub-pixel and the fourth sub-pixel is greater in size than the first sub-pixel and the second sub-pixel, and
• the first sub-pixel added to the second sub-pixel has a size equal to or greater than a size of the third sub-pixel and has a size equal to or greater than a size of the fourth sub-pixel.
