A liquid crystal display device is provided to realize the strong structure against the external impact by stably fixing an optical sensor and a flexible printed circuit board in which the optical sensor is mounted, to a main support. A liquid crystal display device comprises a liquid crystal panel(101), the first printed circuit board(102), a plurality of first flexible printed circuit boards(103), a light source(104), a main support(105), the first coupling groove(105b), an optical sensor(106) and the second flexible printed circuit board(107). On the first printed circuit board, a liquid crystal panel driving part for operating the liquid crystal panel is mounted. The first flexible printed circuit boards connect the liquid crystal panel with the first printed circuit board. The main support receives the light source and liquid crystal panel. |
