• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

An LCD is provided to have the improved brightness by preventing loss of light. A liquid crystal panel(20) displays an image. A plurality of light sources(40) are disposed on a rear surface of the liquid crystal panel to provide light to the liquid crystal panel. A diffusion plate(33) is disposed between the light sources and the liquid crystal panel, and includes a light source receiving part(33a) and a light source isolation part(33b). The light source receiving part surrounds each one of the light sources and protrudes toward the liquid crystal panel. The light source isolation part is disposed between adjacent light source receiving parts and is depressed in a direction opposite to the liquid crystal panel. A reflection part(34) is disposed in the light source isolation part.
