Abstract
A liquid crystal display device includes a first substrate, a second substrate facing the first substrate, a dual passivation layer disposed between the first substrate and the second substrate. The dual passivation layer includes a first passivation layer and a second passivation layer. A refractive index of the first passivation layer is different from a refractive index of the second passivation layer.

A liquid crystal display device comprising:
- a first substrate;
- a second substrate facing the first substrate;
- a liquid crystal layer interposed between the first substrate and the second substrate;
- a gate line disposed between the first substrate and the liquid crystal layer;
- a data line disposed between the first substrate and the liquid crystal layer;
- a pixel connected to the gate line and the data line, the pixel comprising:
- a thin film transistor disposed on the first substrate and connected to a first portion of the data line;
- a pixel electrode connected to the thin film transistor and including an opening formed therein overlapping the thin film transistor;
- and
- a reference electrode disposed on the first substrate and overlapping the pixel electrode, the reference electrode comprising:
- a first connection part disposed substantially parallel to the data line;
- a second connection part disposed substantially parallel to the gate line and connected to the first connection part;
- a branch electrode, comprising:
- a first part;
- a second part connected to the first part;
- and
- a third part connected to the first part and the second connection part, wherein the second part forms a first angle with the first part,
- the third part forms a second angle with the first part and a third angle with the second connection part,
- wherein the thin film transistor comprises a source electrode being a portion of the data line, a drain electrode parallel the data line, and a channel area disposed under the data line and the drain electrode,
- wherein a first opening is formed in the reference electrode overlapping the channel area between the source electrode and the drain electrode.
