Abstract

PURPOSE: To reduce production processes and improve working accuracy of the 3 color parallel type stripe filter of inorganic material by obtaining the third colors out of the cyan, magenta and yellow being of the complementary color relations with red, green and blue are superposed.
CONSTITUTION: A Cu film 2 is evaporated on a face plate 1, thence the film 2 is photoetched to form stripe patterns. After vapor deposition of magenta M, the film 2 is peeld by an etching solution and the magenta M on the film 2 is also removed. Further a Cu film 2A is evaporated on this filter M and the film 2A is photoetched in conformity with the required patterns to leave the film 2A on the magenta M, on which yellow Y is evaporated, thence the film 2A is removed together with the layer Y thereon to form the three color filter of M + Y → R(red). Hence, the vapor deposition times and mask alignment times are reduced and the stripe width may be made to about 10 to 15μm.
