Abstract
A self-light emitting display device with top-emission usually has no film that is capable of light shielding. Therefore, it is necessary to form a light-shielding layer additionally with, which leads the number of processes to increase.
In the present invention, plural films selected from a first coloring layer 161, a second coloring layer 162, and a third coloring layer 163 formed on an opposing substrate are laminated to form a light-shielding portion without using a light-shielding mask.
