ABSTRACT:
Disclosed is a practicable, image display device comprising a color-changing array 2 of a plurality of light-shielding layers 21 and a plurality of color-changing layers 22, of which at least one is a fluorescent layer, as disposed in series on a light-transmissive substrate 1 with being laterally spaced, and an array of a plurality of light-emitting layers 3 as laterally spaced to be in the position corresponding to each color-changing layer 22 in such a manner that the color-changing layers 22 receive emitted light from the light-emitting layers 3 to change it into different colors. The device is characterized in that the surface of the color-changing array 2 that faces the array of light-emitting layers 3 is planarized to thereby reduce its surface roughness to 2.0 .mu.m or lower. The images formed by the device have high visibility with little color mixing and color spread. The producibility of the device is high.
