A liquid crystal panel is mounted in a frame. A positioning component for supporting the liquid crystal panel in a positioned state is attached to the frame using a screw component. A positioning protrusion is provided in the frame. A positioning hole portion into which the positioning protrusion can be inserted is provided in the positioning component. The positioning hole portion has a size such that, in a state in which the positioning protrusion is inserted therein, the positioning component can be moved in a direction in which a support surface of the positioning component approaches or moves away from the liquid crystal panel. A bracket surface that is substantially parallel with a direction in which the support surface of the positioning component approaches or moves away from liquid crystal panel is provided in the positioning protrusion.
