PROBLEM TO BE SOLVED: To display a smooth image and to improve a contrast ratio by adding minute ruggedness to a light emission surface side surface of a frame nearly vertical to a louver arranged between pixels. SOLUTION: A recessed part formed between the pixels constituted of plural LEDs by filler 311 is reduced by the frame 300 provided for every pixel, and reflection light is suppressed by the ruggedness provided on the surface of the frame 300 (B). That is, by forming the frame 300, a surface area due to the filler 311 viewed from a viewer side is reduced. Then, the surface reflection of the frame 310 provided for reducing the curved surface of the filler 311 is dispersed by the ruggedness 317 provided on the frame 310 surface, and the contrast ratio is improved (C). Further, as the used filler 311, epoxy resin, silicon resin, etc., are listed. Further, coloring dye-stuffs and coloring pigments of a dark color system such as black, etc., may be incorporated into these resin for improving the contrast ratio. |
