IMAGE DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

An image display device includes an envelope having a first substrate and a second substrate located opposite the first substrate across a gap and a plurality of pixels provided in the envelope. A plurality of spacers that support an atmospheric load acting on the first and second substrates are provided between the first substrate and the second substrate in the envelope. Indentations with Ra of 0.2 to 0.6 mum and Sm of 0.02 to 0.3 mm are formed covering the whole surfaces of the spacers. An electrically conductive substance is put on the spacer surfaces, thereby forming divided coating films. Since the coating films are divided by the indentations, they can form films of higher resistance that can suppress electric discharge.
