IPS liquid crystal display panel having spacer holes formed between common lines and gate lines
View Patent ↗A liquid crystal display panel according includes a gate line and a data line crossing each other on a first substrate, a common electrode formed in parallel to the data line, a common line connected to the common electrode and arranged in parallel to the gate line, a gate insulating film formed between the gate and data lines to cover the gate line, the common line and the common electrode, a thin film transistor formed at a crossing part of the gate and data lines, a passivation film covering the thin film transistor, the data line and the gate insulating film, a pixel electrode connected to the thin film transistor, a spacer hole penetrating the gate insulating film and the passivation film, and at least one ball spacer formed in the spacer hole.
1. A liquid crystal display (LCD) panel, comprising:
a first substrate and a second substrate that face each other;
a gate line and a data line that are arranged crossing each other on the first substrate;
a common electrode that is formed in parallel to the data line;
a common line that is connected to the common electrode and is formed in parallel to the gate line;
a gate insulating film that is formed between the gate line and the data line and covers the gate line, the common line and the common electrode;
a thin film transistor that is formed at a crossing part of the gate line and the data line;
a passivation film that is arranged covering the thin film transistor, the data line and the gate insulating film;
a pixel electrode that is connected to the thin film transistor;
a spacer hole that penetrates the gate insulating film and the passivation film to expose a portion of the first substrate between the gate line and the common line; and
at least one ball spacer that is arranged in the spacer hole,
wherein the pixel electrode includes:
a first electrode part that is overlapped with the common line such that the gate insulating film is arranged between the first electrode and the common line;
a second electrode part that is formed in parallel to the common electrode to form a horizontal electric field; and
a third electrode part that is overlapped with the gate line such that the gate insulating film is arranged between the third electrode part and the gate line, wherein the spacer hole is formed between the first electrode part and the third electrode part.
2. The LCD panel according to claim 1 , further comprising:
a black matrix that is formed on the second substrate;
red, blue, green color filters that are formed on the black matrix; and
a color filter spacer hole that penetrates the red, blue and green color filters in an area facing the spacer hole.
