  The front surface side positioning portion 92 of the pressing member 200 is configured as a stepped portion protruding from the protruding portion 230 to the front surface side (see FIGS. 12, 15 and 16). In FIG. 12 etc., the case where the said positioning part 92 is each provided in the long side part and short side part of the pressing member 200 is illustrated.

  These front-side positioning portions 92 are in contact with the end face of the liquid crystal panel 52, and thereby the liquid crystal panel 52 is restrained from moving in a direction orthogonal to the Z direction and positioned. Since the front-side positioning portion 92 is provided on both the frame-shaped member 100 and the pressing member 200, the positioning can be performed by the frame body 90 constituted by the two members 100 and 200.

  The frame-like member 100 is configured to further include a front surface side positioning portion 93 (see FIG. 4). The front side positioning portion 93 is configured as a portion of the frame-shaped member 100 that continues from the side portion 120 and protrudes toward the front side with respect to the front frame portion 110. The front side positioning portion 93 faces the end surface of the main body portion 210 of the pressing member 200. For this reason, when attaching the pressing member 200 to the frame-shaped member 100, the positioning portion 93 can be positioned as a guide, and workability is improved.

  The frame-like member 100 and the pressing member 200 can be made of various materials such as resin and stainless steel.

  The case where the liquid crystal shutter 54 having rigidity is accommodated in the frame body 90 has been described above, but the frame body 90 is also suitable when a plate-like member having rigidity other than the liquid crystal shutter 54 is accommodated from the front side. . For example, when the light guide plate 58 is accommodated in the liquid crystal display device 50, or when the light guide plate is accommodated in a liquid crystal display device having a structure without the liquid crystal shutter 54, a liquid crystal display having a structure in which the liquid crystal shutter 54 is replaced with a separate liquid crystal panel. When the separate liquid crystal panel is accommodated in the apparatus, the frame 90 can improve workability. Note that the structure in which the two liquid crystal panels are provided with the separate liquid crystal panels is used for, for example, a liquid crystal display device that displays a stereoscopic image.
