Image display device having a planarized array of reduced surface roughness |
摘要 |
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.
