摘要

PURPOSE: A display device using an optical sensing unit is provided to make the size of a retro reflecting plate attached to a corner part large, thereby increasing light efficiency for the corner part. CONSTITUTION: A housing is placed in a bracket. The bracket is coupled with a corner of a top case(110). A guide structure surrounds the outside of a display panel. The guide structure is coupled with the top case. A retro reflecting plate(210) is attached to the bracket and the guide structure.
