Abstract

A liquid crystal display is provided with a first substrate, a color filter formed on the first substrate, a first electrode formed on the color filter, an interlayer insulating layer formed on the first electrode, a light blocking member formed on the interlayer insulating layer and partially overlapping the first electrode, a second substrate facing the first substrate, a second electrode formed on the second substrate, and a liquid crystal layer interposed between the first and second substrates, wherein the light blocking member and the first electrode may be overlap each other, with the interlayer insulating layer interposed therebetween to form a storage capacitor.

Claims (21)

1. A liquid crystal display comprising:

a first substrate;

a thin film transistor;

a color filter formed on the first substrate and the thin film transistor;

a first electrode formed on the color filter;

an interlayer insulating layer formed on the first electrode;

a light blocking member formed on the interlayer insulating layer and partially overlapping the first electrode;

a second substrate facing the first substrate;

a second electrode formed on the second substrate; and

a liquid crystal layer interposed between the first and second substrates,

wherein the light blocking member and the first electrode overlap each other with the interlayer insulating layer interposed therebetween to form a storage capacitor.

2. The liquid crystal display of claim 1 ,

wherein the thin film transistor comprises:

a gate electrode formed on the first substrate;

a gate insulating layer formed on the first substrate;

a semiconductor layer formed on the gate insulating layer;

a source electrode and a drain electrode formed on the gate insulating layer and the semiconductor layer; and

further comprising:

a passivation layer formed on the data line and the drain electrode.

3. The liquid crystal display of claim 1 , wherein the light blocking member includes a conductive material.

4. The liquid crystal display of claim 3 , wherein a storage voltage is applied to the light blocking member.
