A liquid crystal display device includes a liquid crystal display element, a frame member having a frame-shaped part which is arranged at a displaying surface side of the liquid crystal display element and having a display window exposing a displaying surface of the liquid crystal display element, and a side wall which is extended from the frame-shaped part along a thickness direction of the liquid crystal display element. A light source is arranged opposite to another surface of the liquid crystal display element which is opposite to the displaying surface thereof and irradiates the another surface of the liquid crystal display element with illumination light. A housing member which houses the light source has a main surface opposite to a frame-shaped part of the frame member and a side wall formed at a periphery of the main surface thereof.

In a liquid crystal display device comprising a pair of substrates between which a liquid crystal layer is interposed, a display surface provided on one of the substrates, and a lighting device arranged at a side of another of the substrates, the present invention forms a light shielding film on at least one of side surfaces of the substrates along a direction perpendicular to the display surface and prevents light leak leaking from the lighting device through the at least one of side surfaces.

In order to install a liquid crystal display device comprising a liquid crystal display element, a frame being arranged at a displaying surface side thereof, a light source being arranged at an opposite side to the displaying surface side, and a housing member for housing the light source to an exterior case easily and surely, the present invention provides a screw member to which a fitting screw for fixing the liquid crystal display device to the exterior case is screwed at a side wall of the housing member, a protruded portion being protruded in a thickness direction of the liquid crystal display device at the side wall having the screw member, and an opening which the protruded portion is inserted into in the frame, respectively.
