More Information
Summary:Disclosed is a liquid crystal display (LCD) device having light scattering patterns at an edge region of a light guide plate, capable of preventing a hot spot phenomenon occurring when an edge-type backlight unit is implemented with using light emitting means such as light emitting diodes (LED). The LCD device comprises: an LC panel; a light guide plate disposed below the LC panel, and having light scattering patterns formed in a plurality of groups with a constant gap therebetween at one or more edge regions on an upper surface thereof; and light emitting devices disposed at a side wall of the light guide plate, each light emitting device disposed to correspond to a region between the light scattering patterns, for emitting light.
