Abstract

Disclosed is a liquid crystal display comprising a first substrate; pixel electrodes formed on the first substrate, the pixel electrodes having formed thereon a first aperture pattern; a second substrate provided opposing the first substrate; a common electrode formed on the second substrate, the common electrode having formed thereon a second aperture pattern; liquid crystal material injected between the first and second substrates; and spacers provided between the first and second substrates for maintaining a predetermined gap between the first and second substrates, wherein center portions of the first aperture pattern and the second aperture pattern are substantially straight and formed alternatingly in parallel, and wherein the spacers are positioned at ends of the second aperture pattern.

Claims (35)

1. A liquid crystal display, comprising:
