<p>PURPOSE:To double spuriously the number of color picture elements and to improve image quality by bisecting a transparent member of which the base part is the image screen side of a display device in the area including each color of the color picture elements and forming projecting parts into the shape to stop down the transmitted light on the side opposite from the image screen side. CONSTITUTION:A conductive part 7b contains each color of picture elements and the base part 7a of a transparent base material is extended in the direction of stopping down the approximately bisected and transmitted light. A release part 7c which releases the transmitted light may be flat or spherical. The better effect is obtd. if the part 7b is coated white to prevent transmission of light or is deposited with aluminum, etc. by evaporation so that the light passes only through the part 7c. If the display device is constituted in the above-mentioned way, the quantity of the light from the picture element is not amplified but the light intensity is partially increased and the number of the picture elements is spuriously doubled and therefore the entire part of the image screen is visible bright and fine for the visual sensation of man. The image quality is thus improved. Interpolation of the picture elements is thus resulted. The effect is much improved by preventing irregular reflection of external light with a black mask 8 having no luster.</p> |
