Color display device for electronic paper, and process for production thereof

Abstract

Provided are a color display device capable of colorized display in a reflection type display device which is adopted to electronic paper and the like without degrading the degree of brightness and with high efficiency, and also with ease and lower costs, and a method of producing the same. The color display device includes: a drive-side substrate (3) on which pixel electrodes (2) connected to pixel switches (1) are formed in a given pattern; a transparent substrate (5) including an electrically conductive layer (4); display media (10) which have white color and black color and are electrically charged; a reflection type display element including the display media (10) disposed between the drive-side substrate (3) and the transparent substrate (5), for forming any appropriate image by pixels corresponding to the pixel electrodes (2); and a color filter (11) provided on the transparent substrate (5) side of the reflection type display element, in which the color filter (11) forms pixel regions (14) by defining the pixels with colorless partition walls (13) which are formed on a substrate, and has colored layers (15) formed therein by ejecting colored inks of three colors, which are colored with at least blue (B), green (G), and red (R), by an inkjet method.
