Pixel structure of liquid crystal display
View Patent ↗Disclosed is a pixel structure of a liquid crystal display including: a first substrate with red, green and blue color filters; a second substrate comprising; a TFT; a data bus line carrying a data signal that is applied to the TFT to drive unit pixels; and a gate bus line in which a bump-shaped groove is formed at a region where the gate bus line crosses and overlaps the data bus line to prevent the data bus line from opening and through which a gate signal is applied: wherein current is selectively supplied to the pixel electrode of the unit pixel region defined by the gate bus line and the data bus line so that an electric field is generated between the first substrate and the second substrate; and a liquid crystal layer between the first substrate and the second substrate.
1. A liquid crystal display comprising:
a first substrate with red, green and blue color filters;
a second substrate comprising;
a TFT;
a data bus line carrying a data signal that is applied to the TFT to drive unit pixels; and
a gate bus line in which a bump-shaped groove is formed at a region where the gate bus line crosses and overlaps the data bus line to prevent the data bus line from opening and through which a gate signal is applied:
wherein current is selectively supplied to the pixel electrode of the unit pixel region defined by the gate bus line and the data bus line so that an electric field is generated between the first substrate and the second substrate; and
a liquid crystal layer between the first substrate and the second substrate,
wherein the bump-shaped groove comprises a first portion which is as wide as width of the gate bus line and a second portion which is narrower than the width of the gate bus line.
2. The liquid crystal display according to claim 1 , wherein the bump-shaped groove has an edge that overlaps the data bus line near the center of the data bus line.
3. The liquid crystal display according to claim 1 , wherein the bump-shaped groove has a saw tooth-shaped portion.
4. The liquid crystal display according to claim 1 , wherein the bump-shaped groove is saw tooth-shaped and generally parallel with the gate bus line.
5. The liquid crystal display according to claim 1 , wherein the bump-shaped groove is saw tooth-shaped and narrower than the gate bus line on average.
6. The liquid crystal display according to claim 1 , wherein the bump-shaped groove is formed to be saw tooth-shaped in a groove and narrower than the gate bus line.
7. A liquid crystal display comprising:
a first substrate with red, green and blue color filters;
a second substrate comprising;
a TFT;
a source electrode and a drain electrode formed on an active layer;
a data bus line carrying a data signal that is applied to the TFT to drive unit pixels; and
a gate bus line in which a bump-shaped groove is formed at a region where the gate bus line crosses and overlaps the data bus line to prevent the data bus line from opening and through which a gate signal is applied:
wherein current is selectively supplied to the pixel electrode of the unit pixel region defined by the gate bus line and the data bus line so that an electric field is generated between the first substrate and the second substrate; and
a liquid crystal layer between the first substrate and the second substrate,
wherein the bump-shaped groove comprises a first portion which is as wide as width of the gate bus line and a second portion which is narrower than the width of the gate bus line.
