Abstract
A liquid crystal display panel and method for fabricating the same are disclosed in the present invention. The liquid crystal display panel includes first and second substrates facing into each other, a column spacer in a pixel region between the substrates, a dummy column spacer formed in a dummy region between the substrates, the dummy column spacer having an opened portion in at least one of corner-regions, a UV sealant formed outside the dummy column spacer between the substrates, and a liquid crystal layer between the substrates.
Claims11
A method of manufacturing a liquid crystal display comprising:
- providing a first substrate;
- providing a second substrate;
- forming a column spacer and a dummy column spacer on one of the first and second substrates, the column spacer being formed in a pixel region and the dummy column spacer being formed in a dummy region;
- forming a supplementary dummy column spacer adjacent entirely to the dummy column spacer;
- dispensing a liquid crystal on either the first or second substrate in a region having the column spacer and substantially enclosed by the dummy column spacer, wherein the dummy column spacer is substantially linear at the side region and has at least one opening at at least one corner region;
- forming a seal pattern with a sealant on either the first or second substrate outside the dummy column spacer;
- bonding the first and second substrates;
- wherein the liquid crystal flows through openings in the dummy column spacer and is uniformly filled between the first and second substrates.
A method for fabricating a liquid crystal display panel, comprising:
- forming a column spacer and a dummy column spacer on a first substrate, the column spacer being formed in a pixel region and the dummy column spacer being formed in a dummy region;
- forming a supplementary dummy column spacer adjacent entirely to the dummy column spacer;
- forming a UV sealant outside the dummy column spacer;
- applying a liquid crystal on the second substrate in a region having the column spacer and inside a region substantially enclosed by the dummy column spacer, wherein the dummy column spacer is substantially linear at the side region and has at least one opening at at least one corner region, such that the liquid crystal flows through openings in the dummy column spacer;
- attaching the first and second substrates after applying the liquid crystal on the second substrate;
- and
- irradiating a UV ray on the attached substrates.
