Display device and backlight unit included therein

摘要

A display device includes a display panel, a backlight unit outputting light to the display panel, and an optical member refracting or reflecting the light output from the backlight unit and providing the display panel with the light. The backlight unit includes a light source emitting the light, a light guide plate scattering the light emitted from the light source and irradiating the scattered light to a front surface of the backlight unit, a reflective sheet reflecting the light, which is irradiated to a rear surface of the light guide plate, to the light guide plate, a quantum dot sheet for converting the light, which is irradiated to the front surface of the light guide plate, into a white light, and a light-converting material provided on an edge portion of the reflective sheet to convert the light into the white light.

主权项

1. A display device, comprising:
a display panel; a backlight unit configured to output light to the display panel; and an optical member configured to refract or reflect the light output from the backlight unit and provide the display panel with the refracted or reflected light, wherein the backlight unit comprises:
a light source configured to emit the light;a light guide plate configured to irradiate the light to a first surface of the light guide plate;a reflective sheet configured to reflect the light, which is irradiated from a second surface of the light guide plate, to the light guide plate;a quantum dot sheet configured to convert the light, which is irradiated to the first surface of the light guide plate, into a white light; anda light-converting material applied to the reflective sheet, only to an at least one edge portion of the reflective sheet, and configured to convert the light at the at least one edge portion of the reflective sheet into light capable of being converted to white light when transmitted through the quantum dot sheet.
