Title:
カラーフィルタ、液晶表示装置、カラーフィルタの製造方法
Document Type and Number:
Japanese Patent JP5622052
Kind Code:
B2
Abstract:
A color filter is provided which is formed by using a small mask continuous exposure method in which a portion between adjacent exposed areas is shielded from light by a blind shutter, and which has dummy photo spacers formed on a colored layer outside a display pixel area at a uniform height. Firstly, by using the small mask continuous exposure method, a colored layer is formed which extends in the X-axis direction astride the display pixel area and a frame area. At this time, the edges of the blind shutter which are parallel to the Y axis are each positioned so as to be distant by 500 μm to 1000 μm from a side which forms the outer circumference of the outermost opening and which is closest to the frame area extending in the Y-axis direction. Next, photo spacers are formed on the colored layer such that the central axis of each photo spacer is positioned in a range of positions that are distant by 300 μm or less from a side which is closest to the frame area extending in the Y-axis direction.
