Disclosed is a liquid crystal display module that improves luminance of a liquid crystal panel by enhancing a light transmittance. The liquid crystal display module comprises a liquid crystal panel with plural unit pixels for converting incident light into colored light, wherein each unit pixel includes red (R), green (G), blue (B), and white (W) sub-pixels; a light source for supplying light to the liquid crystal panel; an optical member for guiding light emitted from the light source toward a frontal direction of the liquid crystal panel; and a polarizing means including a polarization area for polarizing the light outgoing from the liquid crystal panel, and a hole for transmitting the light therethrough.
