Abstract
A liquid crystal display having enhanced transmittance in which the pixel electrode includes a micro-slit pattern and overlaps a control electrode on the insulation layer so that an effective voltage difference is formed between the pixel electrode and the control electrode to control the directional characteristics of the liquid crystal molecules.
Claims23
A display panel comprising:
- an array substrate having a first thin film transistor (TFT), a control electrode and a pixel electrode disposed above the control electrode and including a micro-slit pattern;
- an opposite substrate coupled to the array substrate and having a common electrode;
- and
- a liquid crystal layer formed between the opposite substrate and the array substrate and arranged vertically when an electric voltage is not applied to the liquid crystal layer, and
- wherein the control electrode substantially overlaps an entire portion of the pixel electrode in a plan view, and the pixel electrode is connected to the first TFT through a hole passing through the control electrode.
