Liquid crystal display device

Abstract

A liquid crystal display device and a liquid crystal screen module (100) thereof. The liquid crystal display device comprises a liquid crystal screen module (100) and a backlight module (200). A segmentation edge (121) is arranged on a first flexible printed circuit board (120) in the liquid crystal screen module (100). A folded part (122) is defined by the segmentation edge (121), which at least comprises a first folded sub-part (122a). A free end (1222) of the first folded sub-part (122a) is folded to be electrically connected to a second flexible printed circuit board (220) in the backlight module (200). The first folded sub-part (122a) is equivalent to the "|"-shaped part in an existing T-shaped or L-shaped second flexible printed circuit board, so that the second flexible printed circuit board (220) can only adopt the shape of the horizontal straight line-shaped part of the existing T-shaped or L-shaped second flexible printed circuit board, and the second flexible printed circuit board (220) can be formed by means of one-step cutting, which improves the type-setting rate of a flexible printed circuit board, reduces the raw material cost, and also avoids the risk of short circuit or circuit interruption caused by the fact that the second flexible printed circuit board (220) is formed by welding multiple parts to improve the reliability of circuit connection.
