A display device is a device for visually displaying data, and includes a liquid crystal display device, an electrophoretic display device, an organic light emitting display device, an inorganic EL display device (Electro Luminescent Display) A field emission display, a surface-conduction electron-emitter display, a plasma display, and a cathode ray tube display.

In particular, liquid crystal displays (LCDs) are in the spotlight in recent years due to advantages such as mass production technology, ease of driving means, realization of high image quality, and realization of a large area screen.

2. Description of the Related Art Liquid crystal display devices (LCDs) are electronic devices that transmit various electrical information generated from various devices into visual information using a change in liquid crystal transmittance according to an applied voltage. The liquid crystal display device is widely used as an alternative means to overcome the disadvantages of CRT (Cathode Ray Tube), which is conventionally used, because it can realize low power driving, thin structure, and excellent image quality.

Such a liquid crystal display device can largely include a display panel, a circuit portion, and a backlight unit. The display panel functions to display an image by adjusting the amount of transmitted light. The circuit unit functions to apply various signals transmitted from the driving system to the display panel and to control the signals. The backlight unit Is used as a light control device for uniformly irradiating light to the entire display panel.

Specifically, the display panel is made up of two substrates facing each other and liquid crystal interposed therebetween, and displays an image by changing the arrangement of the liquid crystal by an electric field generated between the substrates. A polarizer may be attached to each of the two substrates.

The circuit unit includes various circuit elements and a printed circuit board (PCB) to control the overall operation of the liquid crystal display device.

A backlight unit (BLU) is a light source of a liquid crystal display device, and is a light supply device because a liquid crystal display device can not emit light itself, and is a light-receiving device that displays an image by adjusting the transmittance of light coming from the outside.

Such a backlight unit is divided into an edge type BLU and a bottom type BLU according to the position of a light source. In addition, the backlight unit (BLU) includes a light guide plate and various kinds of optical sheets so as to efficiently transmit and use the light supplied to the light source to the display panel.
