Abstract
A pixel structure of a fringe field switching (FFS) mode LCD is provided, and the pixel structure includes: a scan line, a thin film transistor (TFT), a common electrode, a pixel electrode, and a patterned insulative layer. The pixel electrode is insulatively disposed on the common electrode. The pixel electrode generates a fringe field corresponding to the common electrode. The patterned insulative layer, which is disposed above the scan line and the TFT, is utilized to confine the fringe field so as to reduce disordered electrical field, thereby improving the shortcoming of light leakage.
Claims9
A pixel structure of a fringe field switching (FFS) mode LCD (liquid crystal display), comprising:
- a first substrate;
- a scan line disposed on the first substrate;
- a data line insulatively intersecting the scan line to define a pixel unit;
- a thin film transistor (TFT) disposed in an intersection region of the data line and the scan line;
- a common electrode disposed in the pixel unit on the first substrate;
- a pixel electrode disposed above the common electrode and being insulated from the common electrode, the pixel electrode generating a fringe field corresponding to the common electrode, wherein the TFT and the scan line are covered with the pixel electrode;
- and
- a patterned insulative layer disposed on the scan line and the TFT and exposing the pixel unit, the patterned insulative layer confining the fringe field within the pixel unit, wherein the fringe field in edges of the pixel electrode is pushed inwardly.
