发明名称 SCREEN FOR PRJECTION TYPE DISPLAY DEVICE
摘要 <p>PURPOSE:To display high-quality images by increasing the contrast and chromaticity of displayed images to external light. CONSTITUTION:The vertical striped positions where red, green and blue light rays 14 to 16 are formed among the exit surface 25b side lenses 25c of a lenticular lens screen 25 are provided with red filters 31, green filters 32 and blue filters 33 of the colors corresponding to the vertical stripes. The incident external light on the lens 25c is, therefore, absorbed by the filters 31 to 33 of the respective colors and the chromaticity of the light rays 14 to 16 of the displayed images emitted from the lens 25c are corrected by the filters 31 to 33.</p>
