Patent ID: 8582045

Claim:
A liquid crystal display (LCD) device, comprising: an LC panel having a polarizer on at least an upper surface thereof, and displaying images; a lower cover under the LC panel; a backlight unit being disposed on the lower cover to provide light to the LC panel, the backlight unit including a balance PCB (Printed Circuit Board) disposed at inner sides of the lower cover to drive a plurality of lamps, a reflective layer attached on the lower cover, and a lamp socket mounted on the balance PCB to couple the lamps, the lamp socket being curved in the upper direction in a predetermined angle so that one end portion of the lamp socket is fixed at the balance PCB and another end portion couples the lamps; a protection member being provided on the polarizer, and being made of a tempered substrate for protecting the LC panel from an external impact and an anti-reflect layer reducing a reflectivity of external light by being formed on the tempered substrate; and an adhesive layer being formed from a material having a similar refractivity to the polarizer and the tempered substrate of the protection member, and adhering the protection member onto the LC panel by being interposed therebetween, wherein the differences of each refractivity between the tempered substrate and the adhesive layer and between the adhesive layer and the polarizer are set not to exceed 0.2, wherein the anti-reflect layer is formed on an upper side surface of the tempered substrate, a material having a low refractivity and a material having a high refractivity are alternately formed on the tempered substrate, the material having low refractivity being formed at an uppermost part of the anti-reflect layer so that external light is incident through the material having low refractivity, wherein the anti-reflect layer has a surface formed by an anti-reflect sputtering, wherein the balance PCB is vertically disposed on a bottom of the lower cover and a height of the balance PCB is variable so that a distance between the lamp and the reflective layer is controlled.
