Abstract
A liquid crystal display includes at least one pixel. The pixel includes a first sub-pixel charged with a first voltage and a second sub-pixel charged with a second voltage different from the first voltage. A first sub-pixel electrode provided in the first sub-pixel and a second sub-pixel electrode provided in the second sub-pixel include slits having different widths according to directions. Due to the slits, average directors of the first and second sub-pixels are tilted in a horizontal or vertical direction. Accordingly, a side visibility of the display apparatus is improved.
Claims19
A liquid crystal display comprising:
- at least one pixel including a first sub-pixel charged with a first voltage and a second sub-pixel charged with a second voltage different from the first voltage, the first subpixel and the second sub-pixel are arranged in a first direction;
- a first substrate on which a first sub-pixel electrode provided in the first sub-pixel and a second sub-pixel electrode provided in the second sub-pixel are disposed;
- a second substrate that faces the first substrate and on which a common electrode facing the first sub-pixel electrode and the second sub-pixel electrode is disposed;
- and
- liquid crystals interposed between the first substrate and the second substrate,
- wherein the first sub-pixel electrode comprises at least one first slit having a first extending portion extending in a second direction perpendicular to the first direction and a second extending portion extending in the first direction, wherein the first extending portion includes a first linear edge extending parallel with and adjacent to a first outer edge of the first sub-pixel electrode and a second linear edge extending parallel with the first linear edge, and the second extending portion includes a third linear edge connected to the first linear edge and adjacent to a second outer edge of the first sub-pixel electrode and a fourth linear edge connected to the second linear edge, and a width of the first extending portion is different from a width of the second extending portion.
A liquid crystal display comprising:
- a first substrate that includes a gate line applied with a gate signal and a data line applied with a data signal;
- a pixel electrode disposed on the first substrate;
- a thin film transistor disposed on the first substrate to apply the data signal to the pixel electrode in response to the gate signal;
- a second substrate that faces the first substrate and on which a common electrode is disposed;
- and
- liquid crystals interposed between the first substrate and the second substrate, wherein the pixel electrode comprises at least one first slit that includes a first extending portion extending in a first direction and a second extending portion extending in a second direction perpendicular to the first direction and having a width different from a width of the first extending portion, wherein the first extending portion includes a first linear edge extending parallel with and adjacent to an outer edge of the first subpixel and a second linear edge extending parallel with the first linear edge, and the second extending portion includes a third linear edge connected to the first linear edge and a fourth linear edge connected to the second linear edge.
