a light blocking film affixed to a second side of the second substrate as a second plurality of lines spaced apart from each other,

wherein the light blocking film is formed on the light transmitting film, and

wherein the first electrode overlaps the light blocking film so that centers of ones of the second plurality of lines lie directly over centers of corresponding ones of the first plurality of lines.

2. The panel of claim 1 , wherein the light blocking film is formed of light blocking material.

3. The panel of claim 1 , wherein the light blocking film is arranged to correspond to the shape and position of the first electrode.

4. A liquid crystal display, comprising:

a liquid crystal display panel for displaying images; and

a panel for controlling a viewing angle that is arranged on the liquid crystal display panel, the panel including a first substrate, a second substrate facing the first substrate, a liquid crystal layer interposed between the first and the second substrates, a first electrode formed on the first substrate, and a second electrode formed on a first side of the second substrate to face the first electrode.

wherein a region of the panel for controlling a viewing angle corresponding to the first electrode is displayed as a plurality of first black lines when power is supplied to the panel for controlling a viewing angle; and

wherein the liquid crystal display panel displays second black lines positioned to correspond to the first black lines.

5. The liquid crystal display of claim 4 , wherein the first electrode is formed as a plurality of lines spaced apart from each other.

6. The liquid crystal display of claim 4 , wherein:

the first electrode is formed extending in a columnar direction; and

the liquid crystal display panel includes a thin film transistor substrate and a color filter substrate facing the thin film transistor substrate, the color filter substrate having a plurality of color filters arranged in a matrix form so that an identical column has color filters with different colors.

7. The liquid crystal display of claim 4 , further comprising a light blocking film formed on a second side of the second substrate.

8. The liquid crystal display of claim 7 , wherein the light blocking film is formed of light blocking material.

9. The liquid crystal display of claim 7 , wherein the light blocking film is arranged to correspond to the shape and position of the first electrode.

11. The liquid crystal display of claim 10 , wherein a region of the panel for controlling a viewing angle corresponding to the first electrode is displayed as a plurality of black lines when power is supplied to the panel for controlling a viewing angle.

12. The liquid crystal display of claim 7 , further comprising a light transmitting film arranged on the second side of the second substrate,

wherein the light blocking film is formed on the light transmitting film.

13. A liquid crystal display, comprising:

a first panel; and

a second panel facing the first panel,

wherein the first panel displays a first plurality of black lines by blocking light with a liquid crystal layer when power is supplied to the first panel;

wherein the second panel displays a second plurality of black lines when the first plurality of black lines are displayed; and

wherein the first plurality of black lines overlaps the second plurality of black lines so that centers of ones of the second plurality of black lines lie directly over centers of corresponding ones of the first plurality of black lines when power is supplied to the first panel.
