Abstract:
1. A liquid crystal display module, comprising: an edge light system in which a periphery of a liquid crystal panel, a light guide plate and a reflective sheet laid one upon another are surrounded by a case and a lamp and a reflecting plate are disposed between an incidence surface of the light guide plate and a side of the case; the light guide plate has a wedge-shaped section that an incidence surface of the light guide plate is thicker than an opposite surface of the incidence surface; the liquid crystal panel is disposed so as to be spaced from a front surface of the light guide plate; the reflective sheet is closely adhered to the light guide plate so as to cover substantially an overall rear surface of the light guide plate, the module further comprising: a frame, including opposite right and left longitudinal frame portions and a transverse frame portion connecting lower ends of the right and left longitudinal frame portions to each other and having a larger length than the longitudinal frame portions, the frame being formed into a C-shape, the reflective sheet, the light guide plate and the liquid crystal panel being sequentially laid one upon another inside the frame; a control board disposed at a rear surface side of the frame and connected to the liquid crystal panel by a flat cable; a bezel having a lower face abutting against the transverse frame portion of the frame with the flat cable interposed between the frame and the lower face of the bezel, a left side face abutting against the left longitudinal frame portion, a right side face abutting against the right longitudinal frame portion, and an upper face forming a housing together with the reflective sheet, the light guide plate and the liquid crystal panel sequentially laid one upon another inside the frame without abutting against the frame, the right side face formed with an opening communicating with the housing, the bezel fitted with the frame from the front side so as to cover the frame, the lamp including two cold cathode fluorescent lamps disposed in parallel to each other, and rectangular parallelepiped sockets fitted with both ends of the cold cathode fluorescent lamps respectively, the cold cathode fluorescent lamps coupled to each other and having respective terminals to which leads are connected respectively, the leads extending out of outer faces of the sockets; a reflector formed by bending a metal plate so that the reflector has a C-shaped section and further formed into a shape of a groove including a front face, a rear face both substantially in parallel to each other and a base face connecting the front and rear faces to each other, the groove extending from side to side, the sockets closely adhered to an inside of each face of the groove, with the cold cathode fluorescent lamp held by the reflector along the groove, the reflector reflecting light from the lamp in a predetermined direction; the incidence surface side of the light guide plate protrudes from a C-shaped opening of the frame in the housing; and the reflector is formed so that the front face has a height smaller than a width of the opening and longer than a space between the incidence surface of the light guide plate and the upper face of the bezel; the rear face has a height larger than the width of the opening; the base face is in abutment against the upper face of the bezel and the rear face is in abutment against the rear face of the frame, thereby the reflector is slidingly inserted into the housing.
