A LIGHT-EMITTING DEVICE FOR PROVIDING UNIFORM LIGHT DISTRIBUTION AND A COUNTER-LIGHT UNIT PROVIDED WITH THE LIGHT-EMITTING DEVICE.

摘要

A light emitting device for achieving uniform light distribution and a backlight unit employing the light emitting device. The light emitting device includes: a light reflecting member having light reflecting surfaces by which light is reflected; a light transmitting member formed on the light reflecting surfaces of the light reflecting member and having light emitting surfaces; and a point light source emitting light to the light transmitting member. The light emitting surfaces of the light transmitting member through which light incident from the point light source is emitted include: a flat directly emitting surface facing the point light source, and directly passing light emitted from the point light source to the outside of the light transmitting member; and a curved totally reflecting surface formed around the directly emitting surface, and totally reflecting light emitted from the point light source to the light reflecting member and passing light reflected by the light reflecting member to the outside of the light transmitting member.
