Abstract:
1. A hybrid type liquid crystal display device comprising: a liquid crystal display panel having a display area, and a window area defined within the display area as a part of the display area, wherein an image data is displayed at the window area; a first polarization film disposed at a front surface of the liquid crystal display panel with a size corresponding to the display area and a first polarization axis; a light guide panel disposed at a rear surface of the liquid crystal display panel; a light source disposed at a side surface of the light guide panel for providing a back light into the light guide panel; a second polarization film disposed behind the liquid crystal display panel for polarizing the back light to a second polarization axis perpendicular to the first polarization axis; a reflection sheet disposed at a rear surface of the light guide panel for reflecting the back light to the front surface of the light guide panel, and having an aperture area corresponding to the window area; and a cover bottom disposed at the rear surface of the reflection sheet for housing the light guide panel and the light source, and having an aperture portion corresponding to the window area, wherein an image disposed outside of the liquid crystal display panel is shown in front of the liquid crystal display panel through the window area; wherein the second polarization film includes: a side polarization film disposed on the side surface of the light guide panel and between the light source and the light guide panel, wherein the side polarization film polarizes a portion of the back light corresponding to the window area to have the second polarization axis; and a lower polarization film disposed on the rear surface of the liquid crystal display panel, and having an opening area corresponding to the window area, wherein the lower polarization film polarizes a portion of the back light corresponding to the display area excepting the window area to have the second polarization axis.
