LIGHT GUIDE PLATE AND DISPLAY DEVICE HAVING THE SAME

摘要

A light guide plate includes a light conversion portion which transmits a transmission incident light having a first wavelength, and converts a conversion incident light having the first wavelength to a converted light having a second wavelength; and a light guide portion which guides the transmission incident light and the converted light in a first direction. The light conversion portion includes a light incident surface which receives the transmission incident light and the conversion incident light, an inclined side surface inclined with respect to the light incident surface to form an inclined angle with the light incident surface, quantum dots which convert light having the first wavelength to light having the second wavelength and are distributed in a quantum area on the light incident surface and the inclined side surface, and a reflector adjacent to the inclined side surface in a second direction opposite to the first direction.

主权项

1. A light guide plate comprising:
a light conversion portion at which
a transmission incident light having a first wavelength is transmitted, anda conversion incident light having the first wavelength is converted to a converted light having a second wavelength different from the first wavelength; and a light guide portion which guides the transmitted transmission incident light and the converted light in a first direction away from the light conversion portion, wherein the light conversion portion comprises:
a light incident surface which faces the light source and receives the transmission incident light and the conversion incident light;an inclined side surface inclined with respect to the light incident surface to form an inclined angle with the light incident surface;quantum dots which convert light having the first wavelength to light having the second wavelength, the quantum dots distributed in a quantum area disposed on the light incident surface and on the inclined side surface; anda reflector disposed adjacent to the inclined side surface in a second direction opposite to the first direction.
