See).

Specifically, in order to accurately incorporate the liquid crystal panel into the frame, a dimensional tolerance from the outer shape of the backlight held in the frame serving as a reference position for positioning to the display area of the liquid crystal panel is important. However, in the conventional liquid crystal display device, when the liquid crystal panel is incorporated into the frame, positioning is performed by abutting the corner of the liquid crystal panel housed in the panel housing portion with the corner portion of the panel housing portion provided in the frame. Had gone. That is, since the outer shape of the liquid crystal panel is used as a positioning reference, the outer tolerance of the liquid crystal panel is added to the assembly tolerance, and as a result, the dimensional tolerance from the reference position to the display area of the liquid crystal panel increases. Has occurred. In addition, the liquid crystal panel may be displaced in the plane of the panel storage part after assembly.

The pair of polarizing plates 9a and 9b are arranged such that their transmission axes are orthogonal or parallel to each other in accordance with a display mode such as a normally black mode or a normally white mode. The polarizing plates 9a and 9b are attached to the outer surfaces of the substrates 6 and 7, respectively, so as to cover at least the display area of the liquid crystal panel 2.

  The backlight 3 includes a light source 10 that emits illumination light, and a light guide plate 11 that guides the illumination light emitted from the light source 10 to the liquid crystal panel 2 side. The light source 10 is made of, for example, a light emitting diode (LED), and a plurality of light sources 10 are arranged along one end surface of the light guide plate 11. In addition to the LED, for example, a cold cathode tube or an organic electroluminescence element can be used as the light source 10. The light guide plate 11 is made of a light-transmitting plate material such as acrylic resin, and irradiates the back side of the liquid crystal panel 2 while causing the illumination light emitted from the light source 10 to emit light.

  The frame 4 is made of, for example, a member such as a resin that is formed in a substantially rectangular frame shape as a whole. The panel storage portion 5 is a recess formed inside the frame 4 and has an inner shape corresponding to the outer shape of the liquid crystal panel 2.
