Abstract
An optical unit comprises a frame. A light conductive plate is combined with the frame only and stationary relative thereto.
Claims15
An optical unit comprising:
- a frame;
- and
- a light conductive plate combined with the frame only to be stationary relative thereto.
An optical unit comprises:
- a light conductive plate;
- a light reflective sheet;
- and
- at least one optical sheet on one surface of the light conductive plate, which is one of optical sheets that include a diffusion sheet and a lens sheet,
- wherein the light reflective sheet extends to partially cover the optical sheet and the light conductive plate except a light discharge region on the one surface of the light conductive plate, and the reflective sheet is fast on the light conductive plate at an area portion near the periphery of the light conductive plate.
