Disclosed are a display device and a method for manufacturing an optical member. The display device includes a light source; a plurality of wavelength conversion particles to convert a wavelength of a light generated from the light source; and a tube to receive the wavelength conversion particles, wherein a scattering pattern is formed on at least one surface of the tube.
1. A display device comprising:
a light source;
a plurality of wavelength conversion particles to convert a wavelength of a light generated from the light source; and
a tube to receive the wavelength conversion particles,
wherein a scattering pattern is formed on at least one surface of the tube.
2. The display device of claim 1 , further comprising a light guide plate that receives the light converted by the wavelength conversion particles, wherein the tube includes a first surface directed toward the light guide plate and the scattering pattern is formed on the first surface of the tube.
3. The display device of claim 1 , wherein the tube includes a second surface directed toward the light source, and the scattering pattern is formed on the first surface of the tube.
4. The display device of claim 1 , wherein the scattering pattern is formed on an outer surface of the tube.
5. The display device of claim 1 , wherein the scattering pattern is formed on an inner surface of the tube.
6. The display device of claim 1 , wherein the scattering pattern is formed on both inner and outer surfaces of the tube.
7. The display device of claim 6 , wherein the tube includes glass.
8. The display device of claim 6 , wherein the scattering pattern includes:
a first scattering pattern on the inner surface of the tube; and
a second scattering pattern on the outer surface of the tube,
wherein the first scattering pattern is different from the second scattering pattern.
9. A display device comprising:
a light guide plate;
a display panel on the light guide plate;
a light source at a lateral side of the light guide plate;
a tube between the light guide plate and the light source; and
a plurality of wavelength conversion particles in the tube,
wherein a scattering pattern is formed on the tube.
10. The display device of claim 9 , wherein the scattering pattern is formed on an inner surface of the tube.
11. The display device of claim 9 , wherein the scattering pattern is formed on both inner and outer surfaces of the tube.
