Abstract
This invention relates to a liquid crystal display panel adapted to minimize movement of a spacer, and a fabricating method thereof. A liquid crystal display panel according to an embodiment of the invention includes a black matrix formed on a first substrate and formed in a boundary between pixel areas for dividing the pixel areas; red, green, and blue color filters formed at the divided pixel areas; at least two holes adjacent to each other on the black matrix; at least one dam dividing the adjacent holes; and a spacer restricted within at least one of the at least two holes.
Claims9
A liquid crystal display panel, comprising:
- a black matrix formed on a first substrate and formed in a boundary between pixel areas for dividing the pixel areas;
- red, green, and blue color filters formed at the divided pixel areas;
- at least two holes adjacent to each other on the black matrix, wherein one hole is central to the other;
- at least one dam, wherein the dam divides the adjacent holes and extends between both holes;
- and
- a spacer restricted within at least one of the at least two holes,
- wherein the spacer is restricted to the central hole among two or more holes,
- wherein a common electrode is formed on the first substrate and overlaps with a pixel electrode formed on a second substrate to form a storage capacitor, and the at least two holes and the at least one dam are formed on the black matrix that faces an area where the storage capacitor is formed,
- wherein the spacer is formed by spraying a spacer ball and a solvent held in ink-jet,
- wherein the dam is formed from a single layer,
- wherein the dam is formed entirely on the black matrix.
A fabricating method of a liquid crystal display panel, comprising:
- providing a first substrate;
- forming a black matrix on the first substrate that divides pixel areas in a boundary between the pixel areas;
- forming red, green, and blue color filters in the divided pixel areas;
- forming at least two holes adjacent to each other on the black matrix, wherein one hole is central to the other;
- forming at least one dam, wherein the dam divides the adjacent holes and extends between both holes;
- and
- forming a spacer restricted within at least one of the at least two holes,
- wherein the spacer is restricted to the central hole among the two or more holes,
- wherein the spacer is formed by spraying a spacer ball and a solvent held in ink-jet,
- wherein the dam is formed from a single layer,
- wherein the dam is formed entirely on the black matrix.
