LIQUID CRYSTAL DISPLAY AND MANUFACTURING METHOD THEREOF
First Claim
1. A liquid crystal display, comprising:
- a first substrate;
a first field generating electrode and a second field generating electrode disposed on the first substrate, the first electrode overlapping the second electrode;
an insulating layer disposed between the first electrode and the second electrode; and
a first signal line and a second signal line disposed on the first substrate, the first signal line and the second signal line being connected to the first field generating electrode,wherein the insulating layer comprises a passivation layer disposed between the second signal line and the second field generating electrode,wherein the passivation layer comprises a first portion overlapping the first signal line and the second signal line and a second portion not overlapping the first signal line and the second signal line, andwherein a thickness of the first portion is larger than a thickness of the second portion.

Abstract
In a liquid crystal display (LCD), a thickness of a passivation layer overlapping signal lines is larger than a thickness of portion of the passivation layer not overlapping signal lines. A spacer may be formed to overlap the signal lines. In an aperture region of the LCD, a thickness of the passivation layer between a common electrode and a pixel electrode is relatively small, and therefore, it may be possible to prevent reduction in the intensity of the electric field between the common electrode and the pixel electrode. Since thickness of the passivation layer may be relatively large, it may be possible to prevent a signal delay of common voltage. A spacer may be formed overlapping signal lines with relatively thick passivation layer. The spacer may have a small height. Cell gap may be adjusted to be uniform, and prevent reduction in aperture ratio of the LCD.
