Even when the liquid crystal projector is arranged on the front side, it can be arranged at a corner of a space that is not noticeable, and the user does not feel uncomfortable with the installation of the liquid crystal projector.

In order to achieve the above object, the light emitted from the light source lamp is reflected by the optical reflection plate to bend the light traveling direction, and the bent light is transmitted through the liquid crystal bulb. After projecting into the unit room through the lens after, even if the angle of the light source lamp is changed from -45 degrees to 45 degrees with respect to the plane of the wall,
By adjusting the angle of the optical reflector, an image can be projected to a position desired by the user, and space saving can be realized.

According to another aspect of the present invention, the light emitted from the light source lamp is transmitted through the liquid crystal bulb and then reflected by the optical reflection plate to bend the light traveling direction. By projecting the light source lamp through the lens into the unit room, even if the angle of the light source lamp is changed from -45 degrees to 45 degrees with respect to the plane of the wall,
By adjusting the angle of the optical reflector, an image can be projected to a position desired by the user, and space saving can be realized.

In order to achieve the above object, the present invention provides a liquid crystal display, wherein light emitted from the light source lamp is transmitted through the liquid crystal bulb, and light transmitted through the liquid crystal bulb passes through the lens, and is then reflected by the optical reflection plate. By bending the light source and projecting the bent light into the unit room, the angle of the optical reflector can be adjusted even when the angle of the light source lamp is changed from −45 degrees to 45 degrees with respect to the plane of the wall. By this, the image can be projected to the user's favorite position,
In addition, space saving can be realized.

According to a seventh aspect of the present invention, in the liquid crystal projector, the optical reflector is a mirror or a prism, so that the liquid crystal projector can have a simple structure and is easily available. Therefore, it is possible to reduce costs such as parts purchase cost and assembly cost.

According to another aspect of the present invention, an image display unit installed in the unit room for displaying a projected image has a surface shape that scatters the projected light. In addition, a highlight portion generated by specular reflection does not occur, and a stable image can be shown to the user.
