摘要： PROBLEM TO BE SOLVED: To provide a small-sized, light-weight and bright projection image display device using a reflection type image display element, free from the contrast reduction due to the leaking light during displaying a black image. SOLUTION: A reflection polarizing plate functioning as a polarizing plate by providing a grating function in only the same specific direction is used as a polarizer and an analyzer for the reflection image display element, and the reflection polarizing plates are arranged just before and behind the reflection image display element on the optical path. As for the optical unit for a reflection liquid crystal projector and a reflection liquid crystal projector, by having such a configuration by using the reflection polarizing plate functioning as a polarizing plate having the grating function in only the specific direction, it is unnecessary to install a PBS prism and a 1/4 wavelength plate for correcting the PBS prism. Besides, the interference of structural components for holding a projection lens and a reflection liquid crystal panel is prevented, then, the contrast is enhanced without reducing the resolution, the number of components is reduced (brightness is enhanced) and the device is made small in size and light in weight.

摘要： PROBLEM TO BE SOLVED: To reduce a production cost and power consumption of a liquid crystal display device, using LEDs as a light source by reducing the number of LEDs.
SOLUTION: A backlight is constituted of LEDs 30 arranged on a wiring circuit board 40, which are made to correspond to a light guide plate 50 in which light guide blocks 51 are arranged into a matrix form. By making the number of LEDs 30 corresponding to the light guide blocks 51, arranged near the periphery reduced to less than the number of the LEDs 30 that correspond to the light guide plate blocks 51 arranged near the center, the number of the LEDs 30 that the backlight uses is reduced. If the luminance of the periphery of the display panel is 60% or more of luminance of the center of the panel, unevenness of luminance cannot be recognized by human eyes. According to this, production cost and power consumption of the liquid crystal display device are reduced.
