There is provided a lamp fixing holder. A lamp fixing holder for fixes a lamp to a receiving container. The lamp provides a liquid crystal display panel with light. The lamp includes a first portion of a face and a second portion of the face. The light emitted from the first portion of the face advances toward the liquid crystal display panel. The lamp fixing holder comprises a lamp fixing body and a fixing member. The lamp fixing body holds a third portion of the face of the lamp. The second portion includes the third portion. The fixing member fixes the lamp fixing body to the receiving container. The lamp fixing holder according to the present invention fixes the lamp so that the lamp does not sway, while minimizing an amount of light that is shielded by the lamp fixing holder.

Disclosed is an LCD device including a noise shielding member. The noise shielding member is a transparent conductive member including a transparent film on which a transparent conductive layer is coated. The noise shielding member may also be a transparent conductive layer scattered on the optical sheets. The transparent conductive layer comprises ITO or IZO. The noise shielding member is disposed under the diffusing plate or interposed between optical sheets. The noise shielding member may be disposed under the LCD panel. The noise generated from the electric power signal applied to the lamp of the backlight assembly is shielded from the LCD panel. Furthermore, the noise shielding member and optical sheets contacts with the chassis of the LCD device through various ground members so as to be connected to earth potential and be electrically stabilized. Accordingly, display quality of the LCD device is improved.
