請求の範囲第１項の装置。[Claims for Utility Model Registration] In a TV projector that projects light transmitted through a liquid crystal panel onto a screen via a projection lens, there is provided a means for locking a reflection plate in front of the projection lens; A liquid crystal TV projector characterized by having means for detecting the presence or absence of an image and supplying a left/right switching signal to the liquid crystal panel for switching between right and left images displayed on the liquid crystal panel. The means for supplying the left/right switching signal to the liquid crystal panel includes a changeover switch that can be operated by the user and automatically switches depending on the presence or absence of a reflector, and when there is no reflector, the output of the changeover switch is output as is. 2. The device according to claim 1, which is a registered utility model and comprises switching means for inverting and outputting the output of the switching switch when a reflecting plate is present.
