Method for manufacturing multicolored plate, multicolored filter and multicolored display device

摘要

A multicolor display device and its method of manufacture which comprises providing first and second spaced and opposed substrates, forming a pattern of separate groups of display electrodes on the surface of the first substrate which faces the second substrate, depositing and electrolytically oxidizing an aluminum film on each display electrode, dying the oxidized films on each separate group of display electrodes a color tone which is different from the color tones of the other display electrode groups, forming a counter electrode pattern on the surface of the second substrate, and disposing a display material in the space between the spaced apart first and second substrates.
