Abstract: PURPOSE: A LCD is provided to minimize optical loss and utilize Brewster's law to improve brightness. CONSTITUTION: A LCD comprises a LCD panel(31), a light source(33) and first/second reflection films(35,36). A polarized film(32) is deposited only on a front surface of the LCD panel(31). Light radiated from the light source(33) is reflected a parallel reflection film(34) such as a concave mirror to be converted into parallel light and then be incident to the first reflection film(35) with Brewster's angle. The light is then reflected toward a rear surface of the LCD panel(31) through the second reflection film(36). Therefore, the brightness of the LCD is greatly enhanced and the contrast of images focused on a screen become clear.
