Abstract

The invention provides a backlight module and a liquid crystal display device. The backlight module comprises a back plate, a plurality of light emitting units disposed on the back plate, and a side reflector plate being connected to the back plate and encircling the plurality of light emitting units. The back plate includes a bottom plate and a side wall vertically connected to the bottom plate.The side reflector plate includes a plurality of slope segments connected in sequence; one end of one slope segment being close to the bottom plate among the plurality of slope segments is connected to the bottom plate; and one end of the slope segment being close to the side wall among the plurality of slope segments is connected to the side wall. Included angles between the plurality of slope segments and the bottom are acute angles and are reduced successively. Therefore, phenomena that light from the light emitting unit close to the side reflector plate is emitted directly to form brightlylines at the edge around the backlight module and the light from the light emitting unit away from the side reflector plate can not be emitted to the edge around the backlight module to form dark lines at the edge around the backlight module can be avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a liquid crystal display device. Background technique [0002] Thin Film Transistor (TFT) is the main driving element in current Liquid Crystal Display (LCD) and Active Matrix Organic Light-Emitting Diode (AMOLED). It is related to the display performance of the flat panel display device. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter (ColorFilter, CF) substrate, and apply pixel voltage on the two substrates respectively. and the common voltage, through the electric field formed between the pixel voltage and...
