<p>PURPOSE: A display device using an optical sensing unit is provided to prevent a recursive reflective plate from being slid by forming a prevention protrusion in a location adjacent to a light source of an infrared ray. CONSTITUTION: Infrared sensor modules include a light source of an infrared ray and sensor units(124,154,184) for sensing the change of the infrared ray. A light emitting unit includes a hole for emitting the infrared ray. A main body includes a light receiving unit. The light receiving unit configures a hole for emitting the infrared ray. Brackets(130,160,190) includes a reflective plate prevention protrusion and prevents a recursive reflective plate from covering the sensor unit.</p> |
