LIGHTING EQUIPMENT, LIGHT GUIDE BODY AND LIQUID CRYSTAL DISPLAY DEVICE, ESPECIALLY REGARDING TO PREVENTING THE PROPAGATION LIGHT FROM LEAKING OUT ON A SIDE OPPOSITE TO THE LIGHT EMITTING SURFACE

摘要

PURPOSE: An LCD device is provided to comprise a light guide plate for emitting a light from a light emitting surface, and to form a prism shape for emitting a propagation light of the light guide plate to the light emitting surface by reflecting the propagation light. CONSTITUTION: An LCD device consists of a front light(10) and an LCD panel(20) installed on a rear side. The front light(10) consists of a transparent light guide plate(12), a bar light guide body(13) installed along a side section(12a), and a luminous element(15) installed on at least one section in length direction of the bar light guide body(13). The LCD panel(20) is composed of an upper substrate(21) and a lower substrate(22). A rectangular area(20D) becomes a display area of the LCD panel(20), while a pixel within the display area(20D) is formed in matrix type.
