Liquid crystal display

1. A liquid crystal display, comprising:

a first substrate;

a gate line disposed on the first substrate;

a gate insulating layer disposed on the gate line;

a semiconductor layer disposed on the gate insulating layer;

a data line disposed on the semiconductor layer;

a drain electrode disposed on the semiconductor layer;

a passivation layer which covers the data line and the drain electrode;

a common electrode disposed on the passivation layer;

an interlayer insulating layer disposed on the common electrode;

a pixel electrode disposed on the interlayer insulating layer;

an additional insulating layer disposed on the pixel electrode;

a second substrate disposed opposite to the first substrate; and

a black matrix disposed on the second substrate, wherein the black matrix comprises:

a vertical portion which covers the data line; and

a horizontal portion which covers the gate line and the drain electrode,

wherein

the additional insulating layer is disposed in an opening portion exposed through the black matrix, and

an empty portion is defined through the additional insulating layer in a light blocking portion corresponding to the black matrix.

2. The liquid crystal display of claim 1 , further comprising:

an organic layer disposed on the passivation layer.

3. The liquid crystal display of claim 1 , wherein

a thickness of the additional insulating layer is in a range of about 1,000 Å to about 3,000 Å.
