Abstract

PURPOSE:To thoroughly eliminate the generation of a color deviation when a display pattern is observed from a diagonal direction by providing color filters to cover the entire surface of picture element electrodes. CONSTITUTION:The red, green and blue color filters 6R', 6G', 6B' are respectively formed on the individual picture element electrodes 3 formed on an upper substrate 1 in such a manner that the entire surface including the front and side faces of the electrode pattern is thoroughly coated with the filters. All the light beams trasmitting the picture element electrodes 3 are thereby passed through the corresponding color filters 6R', 6G', 6B' of the respective colors and are transmitted in the front surface direction; therefore, the generation of the color deviation is thoroughly eliminated even if the display pattern displayed on the front surface side of the upper substrate 1 is viewed from the diagonal direction. The color display pattern of a high grade is thus made visible.
