(a) Field of the Invention
The present invention relates to a vertically aligned liquid crystal display, and more particularly, to a vertically aligned liquid crystal display having a aperture pattern formed in electrodes to obtain a wide viewing angle.
(b) Description of the Related Art
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention, and, together with the description, serve to explain the principles of the invention:
FIG. 1 is a partial sectional view of a conventional vertically aligned liquid crystal display;
FIG. 2 is a partial sectional view of a vertically aligned liquid crystal display according to a first preferred embodiment of the present invention;
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
FIG. 2 shows a partial sectional view of a vertically aligned liquid crystal display according to a first preferred embodiment of the present invention.
A pixel electrode 11 is formed on a lower substrate 10, the lower substrate 10 being made of an insulating material such as glass, and a common electrode 21 is formed on an upper substrate 20, which is also made of an insulating material. A first aperture pattern P1 and a second aperture pattern P2 are formed respectively in the pixel electrode 11 and the common electrode 21. Apertures of the first aperture pattern P1 are provided alternately with apertures of the second aperture pattern P2. Plateaus 14 are formed on the lower substrate 10. The pixel electrode 11 is formed over the plateaus 14 such that stepped portions are formed. The plateaus 14 are formed by a gate insulating layer 12 and a protection layer 13.
