Abstract:
1. A liquid crystal display device, the device comprising: a first substrate and a second substrate; a gate line and a data line that intersect vertically and horizontally with each other on the first substrate for defining a plurality of color display pixels and a viewing angle control pixel; a thin-film transistor having a gate electrode, a source electrode, and a drain electrode, which is at each region intersected by the gate line and the data line on the first substrate; a backlight shielding pattern at a circumferential region of the viewing angle control pixel on the first substrate; a first pixel electrode connected to the drain electrode of the thin-film transistor, which is at the color display pixels on the first substrate; a second pixel electrode connected to the drain electrode of the thin-film transistor, which is at the viewing angle control pixel on the first substrate; a protective film on the gate line, the data line, the thin-film transistor, the first electrode, and the second pixel electrode, wherein a first contact hole exposes part of the backlight shielding pattern; a first common electrode connected to the backlight shielding pattern through the first contact hole of the protective film, which is overlapped with at least part of the first pixel electrode, part of the thin-film transistor, and part of the backlight shielding pattern, wherein a plurality of slits overlapped with the first pixel electrode are formed; and a second common electrode formed by corresponding to the first pixel electrode on the second substrate.
