• 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

PURPOSE:To lessen the change in the temp. distribution on a display surface by supporting a light transmission plate approximately by its thickness so that a frame body can be formed extremely thin and regulating the heat radiated from the light transmission plate with a light source side thereby maintaining the specified temp. approximately up to the center of a display surface. CONSTITUTION:The light transmission plate 4 is disposed on the lower side of a liquid crystal cell 1. The liquid crystal cell 1 and the light transmission plate 4 are supported by the frame. The front surface of the light transmission plate 4 is supported by the frame at the front surface and the rear surface and the rear end is supported from the front surface. Both side parts are supported from the rear surface which is the direction different from the supporting direction of the rear end. The wire-shaped light source 5 is disposed along the side of the rear end. A heat equalizing plate 8 consisting of a resin plate is disposed across the light source side on the rear surface of the light transmission plate 4 disposed below the liquid crystal cell 1 and the rear surface of the light source 5.
