LIQUID CRYSTAL DISPLAY DEVICE WITH IMPROVED VIEWING ANGLE AND BRIGHTNESS

摘要

An LCD(Liquid Crystal Display) device with an improved viewing angle and luminance is provided to enable light polarized by a polarizing light guide plate to be incident on an LCD panel, thereby minimize a loss of the light by an absorbing polarizing plate and improving optical efficiency to acquire high luminance with low power consumption and maintaining constant luminance. An LCD device includes a light source unit(100), a polarizing light guide plate(200), an LCD panel(300), and a diffusing layer(390). The polarizing light guide plate has a light incident surface(210a) on which non-polarizing light radiated from the light source unit is incident, and polarizes and collimates, and emits the incident light. The LCD panel modulates the light emitted from the polarizing light guide plate to form an image. The diffusing layer diffuses the light modulated in the LCD panel.
