Abstract

In a vertically aligned liquid crystal display device for controlling liquid crystal molecules alignment in voltage application by providing linear structures or linear slits consisting of a plurality of constituent units to at least one of a pair of substrates having an electrode thereon, there is provided alignment controlling means for forming an alignment singular point s=−1 of liquid crystal molecules at an intersecting point between the structures on the pixel electrode or the slits in the electrode and an edge of a pixel electrode on one of the substrates.

Claims (9)

1. A thin film transistor substrate comprising:

a storage capacitance forming electrode formed on a first substrate;

an active element formed on the first substrate; and

a pixel electrode formed on the first substrate to be connected to the active element, and divided into at least three areas by slits;

wherein electrical connection of one area of the three areas of the pixel electrode to another area has a plurality of routes passing through different areas and at least two of the routes of the electrical connection are provided to oppose electrically to the storage capacitance forming electrode.

2. A thin film transistor substrate according to claim 1 , wherein areas of the pixel electrodes opposing to the storage capacitance forming electrode are different.

3. A thin film transistor substrate according to claim 1 , wherein thicknesses of dielectric layers are different in areas opposing to the storage capacitance forming electrode every route opposing to the storage capacitance forming electrode.

4. A thin film transistor substrate according to claim 1 , wherein storage capacitance values are different every route opposing to the storage capacitance forming electrode.

5. A liquid crystal display device including a thin film transistor substrate set forth in any one of claims 1 to 4 .
