Liquid crystal display device having a container module with a novel structure
A liquid crystal display device includes a display unit, a back light assembly having a light source, a light guiding plate, a light focusing portion, and a mold frame divided into a first frame and a second frame. The mold frame receives the display unit and the back light assembly. The first frame receives the light guiding plate and the light focusing portion and the second frame receives the light source. A reflection sheet is integrally formed at an inner surface of the second frame so as to perform the function of a lamp reflector. Accordingly, a lamp cover is not required so that the number of parts and the manufacturing cost are reduced. A lamp can be exchanged by simply separating the second frame from the mold frame, so failure of the light source caused by friction with other elements is reduced when exchanging the lamp.
1. A mold frame structure comprising:
a first mold defining a polygonal shape except for a first side; and
a second mold detachably combined with the first mold to define the first side, wherein the first and second molds have a cross-sectional shape having a first stepped portion for supporting at least one optical sheet having the polygonal shape and a second stepped portion for supporting a liquid crystal display panel, and
the first and second stepped portions are disposed such that the liquid crystal display panel is disposed over at least one optical sheet, when at least one optical sheet and the liquid crystal display panel are disposed over the mold frame structure.
2. The mold frame structure of claim 1 , wherein the polygonal shape is rectangular.
3. The mold frame structure of claim 2 , wherein the second mold comprises a first groove for receiving a lamp, the first groove being formed at an inner side of the second mold.
4. The mold frame structure of claim 3 , wherein the second mold further comprises a lamp reflecting layer formed on a surface of the first groove to reflect light generated from the lamp.
5. The mold frame structure of claim 3 , wherein the second mold comprises a second groove for receiving a lamp wiring transmitting electric power to the lamp.
6. The mold frame structure of claim 5 , wherein the second groove is formed at an outer side of the second mold, such that the first groove is opposite to the second groove.
7. A liquid crystal display device comprising:
a liquid crystal display panel displaying an image;
a backlight assembly providing the liquid crystal display panel with light, the backlight assembly comprising a lamp generating the light and an optical member for enhancing optical characteristics of the light; and
a mold frame structure comprising:
a first mold defining a rectangle except for a first side; and
a second mold detachably combined with the first mold to define the first side, wherein the first and second molds have a cross-sectional shape having a first stepped portion for supporting the optical member, and a second stepped portion for supporting the liquid crystal display panel.
8. The liquid crystal display device of claim 7 , wherein the second mold comprises a first groove for receiving the lamp, the first groove being formed at an inner side of the second mold.
9. The liquid crystal display device of claim 8 , wherein the second mold further comprises a lamp reflecting layer formed on a surface of the first groove to reflect light generated from the lamp.
10. The liquid crystal display device of claim 8 , wherein the second mold comprises a second groove for receiving a lamp wiring transmitting electric power to the lamp.
11. The liquid crystal display device of claim 10 , wherein the second groove is formed at an outer side of the second mold, such that the first groove is opposite to the second groove.
