发明名称 Color filter manufacturing method, color filter manufactured by the method, and liquid crystal device employing the color filter
摘要 A color filter manufacturing method comprises the steps of forming, on a substrate, a photosensitive layer that increases or develops hydrophilic property upon irradiation of light; exposing the photosensitive layer to light for patterning to form hydrophilic areas in which hydrophilic property is relatively high and non-hydrophilic areas in which hydrophilic property is lower than the hydrophilic areas; and applying a setting ink to the hydrophilic areas with an ink jet technique, thereby forming colored portions. A color filter includes at least a photosensitive layer formed on a substrate and having hydrophilic areas in which hydrophilic property is increased or developed upon irradiation of light, and colored portions formed on the hydrophilic areas of the photosensitive layer. A liquid crystal device is constructed by using the color filter. The color filter can be manufactured inexpensively with the reduced number of steps while satisfying requisite characteristics. Color mixing, color unevenness and uncolored dots are prevented and a highly reliable color filter is provided.
