Abstract

A first display unit according to the disclosure includes a first pixel and a second pixel each having a light emitting layer, and a color filter layer disposed to face the first pixel and the second pixel. The color filter layer has a plurality of regions at a position facing at least the first pixel. The plurality of regions vary in optical transmittance. A second display unit according to the disclosure includes a first pixel and a second pixel each having a plurality of sub-pixels, and a color filter layer disposed to face the first pixel and the second pixel, and having a plurality of color regions having an arrangement of colors in units of the sub-pixels. At least one of the sub-pixels that correspond to a color arrangement configuration of the color regions that face the first pixel is different, in optical transmittance, from corresponding one of the sub-pixels that correspond to a color arrangement configuration of the color regions that face the second pixel.
