摘要： PURPOSE: An LCD having a rear light source of a local transmissive light source is provided to reflect incident sunlight with a sufficient amount by a reflecting layer when a front side of an LCD is exposed to strong sunlight, and to condense emitted lights before the lights pass through optical channels, thereby increasing an intensity of illumination of the LCD. CONSTITUTION: A high-quality reflecting layer(51) is located on the bottom of an LCD(5). The reflecting layer(51) includes plural optical channels(52). The LCD(5) and the reflecting layer(51) are combined together by a glass shade(53) in singular structure. A micro lens film(6) is disposed on the bottom of the LCD(5). The micro lens film(6) includes several optical collection sections(61) functioning as condensers. A rear light source(7) is disposed behind the micro lens film(6). The rear light source(7) operates with an optical guide plate(71). A cold cathode fluorescent tube(72) is located behind the optical guide plate(71). A diffusive film(8) and a condenser(9) are located between the micro lens film(6) and the rear light source(7).
