Pixel structure and liquid crystal display structure using the same

A liquid crystal display structure, comprising:

• a substrate on which a data line and a first electrode are disposed;
• a first dielectric layer directly covering the data line;
• a second dielectric layer disposed on the substrate, wherein the second dielectric layer covers the first electrode and the first dielectric layer,
• wherein a thickness of the second dielectric layer is smaller than a thickness of the first dielectric layer, and satisfying the following equation
• u1*A1/d1<u2*A2/d2,
• wherein A1 denotes an area of the first dielectric layer overlapping the data line, d1 denotes the thickness of the first dielectric layer and u1 denotes a permittivity of the first dielectric layer, A2 denotes an area of the second dielectric layer overlapping the pixel electrode, d2 denotes the thickness of the second dielectric layer and u2 denotes permittivity of the second dielectric layer,
• an opposite substrate parallel and opposite to the substrate;
• and
• a liquid crystal layer disposed between the substrate and the opposite substrate.
