Abstract
In a high-resolution liquid crystal display with improved side visibility, a unit pixel includes first and second sub-pixels in which liquid crystals are continuously aligned and electrically connected. An electric-field reducing layer is located on a pixel electrode for implementing the second sub-pixel, so that a liquid crystal application voltage applied to the second sub-pixel is lower than that applied to the first sub-pixel.
Claims20
A liquid crystal display (LCD) comprising:
- a unit pixel including gate lines and data lines overlapping the gate lines;
- a storage line passing through the unit pixel;
- a thin film transistor in the unit pixel;
- a storage electrode electrically coupled to a drain electrode of the thin film transistor, the storage electrode being located in a region of the unit pixel overlapping with the storage line;
- a pixel electrode in a region in the unit pixel, the pixel electrode being electrically coupled to the storage electrode through a contact hole located in a region of the unit pixel overlapping with the storage line;
- and
- an electric-field reducing layer on the pixel electrode,
- wherein the unit pixel includes a first sub-pixel in a first region of the pixel electrode, which does not overlap with the electric-field reducing layer, and a second sub-pixel in a second region of the pixel electrode, which overlaps with the electric-field reducing layer.

A liquid crystal display (LCD) comprising:
- a unit pixel including gate lines and data lines overlapping the gate lines, the unit pixel including a first sub-pixel and a second sub-pixel electrically coupled to each other;
- a storage capacitor shared by the first sub-pixel and a second sub-pixel;
- a thin film transistor in the unit pixel and shared by the first sub-pixel and a second sub-pixel;
- and
- an electric-field reducing layer overlapping the second sub-pixel and configured to lower an application voltage applied to the unit pixel so that a lower voltage is applied to the second sub-pixel than the first sub-pixel.
