Abstract
Embodiments relate to a light path control device, including a first viewing angle control member including light-shielding patterns patterned at regular intervals and a pattern cover layer to cover the light-shielding patterns; and a diffractive transmitting layer that is disposed on a lower portion of the first viewing angle control member and includes a plurality of slits, and a display device including the light path control device.
Claims20
A light path control device, comprising:
- a first viewing angle control member including light-shielding patterns positioned at regular intervals;
- a pattern cover layer encasing the light-shielding patterns;
- and
- a diffractive transmitting layer disposed on a lower portion of the first viewing angle control member, the diffractive transmitting layer including a plurality of slits.

A display device, comprising:
- a substrate;
- a backlight unit that is disposed on the substrate and configured to generate light;
- a display panel that is disposed on the backlight unit and displays an image using the light provided from the backlight unit;
- and
- a light path control device that is interposed between the backlight unit and the display panel and controls an emission angle of the light incident from the backlight unit and provides the light to the display panel,
- wherein the light path control device comprises:
- a first viewing angle control member including light-shielding patterns patterned at regular intervals;
- a pattern cover layer encasing the light-shielding patterns;
- and
- a diffractive transmitting layer disposed on a lower portion of the first viewing angle control member, the diffractive transmitting layer including a plurality of slits.
