Abstract
A light dimming dot pattern is provided for an LCD in which the diameter of dots is changed in a range from approximately 0.16 mm to approximately 0.65 mm depending on the distance of the dots from a fluorescent tube () in such a manner that the volume of the shielded light is increased and decreased at a location close to a position overlying the fluorescent tube () and at a location remote from the fluorescent tube (), respectively. In this manner, a light dimming dot pattern with a transmittance for all light rays of approximately 62% (roughly in the vicinity of 62%), higher than the transmittance for all light rays in the conventional technique not higher than 50%, is produced. Consequently, the light of uniform high luminance may be produced without raising the luminance of the fluorescent tube (), and hence an LCD of high luminance may be realized.
