Description

本発明は、スクリーンに映像を投影する投射型表示器を備えた表示装置に関するものである。   The present invention relates to a display device including a projection display that projects an image on a screen.

従来より、投射型表示器からスクリーンに映像を投影する表示装置が提案されており、例えば特許文献1,特許文献2に開示されている。斯かる表示装置は、1個のスクリーンに複数の投射型表示器から映像を投影するものであり、各投射型表示器から投影される映像は、各々、スクリーンの所定領域に投影される。前記所定領域は、横方向に並設されるか、若しくは、マトリクス状に配設される。このような表示装置は、大きなスクリーンに高精細な映像を表示することができるという利点を有している。   Conventionally, a display device that projects an image from a projection type display onto a screen has been proposed. For example, Patent Documents 1 and 2 disclose. Such a display device projects images from a plurality of projection displays on a single screen, and each image projected from each projection display is projected onto a predetermined area of the screen. The predetermined regions are juxtaposed in the horizontal direction or arranged in a matrix. Such a display device has an advantage that a high-definition image can be displayed on a large screen.
