Abstract
A film adhered on a display panel includes a black layer for preventing an external light from entering into the display panel, and a reflective layer for preventing light emitted from the display panel from being absorbed in the black layer. The film minimizes the influence of an external light and improves transmittance, thereby providing a user with a good-quality picture.
Claims21
A film adhered on a display panel, the film comprising:
- a light guide for refracting light emitted from the display panel and for emitting the light in a vertical direction with respect to the display panel;
- a black layer for preventing an external light from entering into the display panel, wherein the black layer is adhered on a lower surface of the light guide;
- and
- a reflective layer for preventing light emitted from the display panel from being absorbed in the black layer, wherein the reflective layer is formed on a lower surface of the black layer.
