Abstract
A display device with improved viewing angle characteristics is provided. A display device with suppressed mixture of colors between adjacent pixels is provided. The display device includes a first coloring layer, a second coloring layer, and a structure body therebetween. The structure body has a portion closer to a display surface side than a bottom surface of the first coloring layer or a bottom surface of the second coloring layer.
