NARROW VIEW ANGLE DISPLAY DEVICE AND SWITCHABLE WIDE/NARROW VIEWING ANGLE DISPLAY DEVICE

摘要

A narrow viewing angle display device and a display device capable of wide/narrow viewing angle switching are provided to implement a narrow viewing angle mode and a wide viewing angle mode by transmitting or blocking light incident onto a liquid crystal panel or output light or changing a light path. A display panel implements an image. A backlight(220) supplies light to the display panel. A switching liquid crystal panel is provided on the display panel, implements a wide viewing angle mode by uniformly transmitting light output from a display panel when a signal is not applied, and implements a narrow viewing angle module by blocking light output to an image un-observed region when the signal is applied. The display panel includes a liquid crystal panel(210).
