Liquid crystal display backboard

The invention discloses a liquid crystal display backboard, and the backboard comprises a backboard body, a main control panel, a light source panel, a light guide plate, a diffusion plate, a circuitboard, a vertical polarizing plate, a rear glass substrate, liquid crystal, a color filter plate, a front glass substrate, a horizontal polarizing plate and a panel which are arranged in sequence; a light mixing area is arranged outside the light source panel, and the light guide plate is arranged at an opening of the light mixing area. According to the technical scheme, the light mixing area is arranged, light sources are concentrated and can be completely emitted out of the light guide plate, and the situation that the overall quality of the back plate and control over the light sources areaffected due to the fact that the light sources leak from the periphery of the light source plate is avoided. 本发明公开了一种液晶显示器背板，包括依次设置的背板、主控制板、光源板、导光板、扩散板、电路板、垂直偏光板、后玻璃基板、液晶、彩色滤光板、前玻璃基板、水平偏光板和面板，所述光源板外部设置有混光区，所述导光板设置在混光区口部；本发明技术
