Abstract

A liquid crystal display includes: a pair of substrates, which face with each other, wherein at least one of the pair of substrates is made of ultra-thin glass; a liquid crystal member arranged between the pair of substrates; a main seal pattern arranged between the pair of substrates to bond the pair of substrates and to surround and seal the liquid crystal material; and a gap maintaining member, which is arranged to at least a substrate edge in the vicinity of a substrate edge formed by cutting the at least one of the substrates made of the ultra-thin glass, and which maintains a distance between the pair of substrates in a predetermine range.

Claims

1. A liquid crystal display comprising:

a pair of substrates, which face with each other, wherein at least one of the pair of substrates is made of ultra-thin glass;

a liquid crystal member arranged between the pair of substrates;

a main seal pattern arranged between the pair of substrates to bond the pair of substrates and to surround and seal the liquid crystal material; and

a gap maintaining member, which is arranged to at least a substrate edge in the vicinity of a substrate edge formed by cutting the at least one of the substrates made of the ultra-thin glass, and which maintains a distance between the pair of substrates in a predetermine range.

2. The liquid crystal display according to claim 1,

wherein the gap maintaining member is formed to be separated from the main seal pattern.

3. The liquid crystal display according to claim 2,

wherein the gap maintaining member includes an opening,

wherein the opening is opened from a space formed between the gap maintaining member and the main seal pattern to outside of a region surrounded by the gap maintaining member.

4. The liquid crystal display according to claim 1,

wherein the gap maintaining member is formed to fill a region from the substrate edge to the main seal pattern.

5. The liquid crystal display according to claim 1,

wherein column spacers are arranged on a display region to maintain the distance between the pair of substrates in the predetermined range, and

wherein the gap maintaining member is made of the same material as the column spacers and has the same height.

6. The liquid crystal display according to claim 1,

wherein spacers are mixed into the main seal pattern to maintain the distance between the pair of substrates in the predetermined range, and

wherein the gap maintaining member is made of the same material as the main seal pattern.

7. A method of manufacturing a liquid crystal display described in claim 6, comprising:

preparing a pair of mother substrates;

forming a main seal pattern having a plurality of seal regions configured to surround and seal liquid crystal material, on one of the pair of mother substrates;

dropping liquid crystal member in the plurality of seal regions of the main sealant; and

forming a united configuration, in which the main seal patterns and the gap maintaining member arranged between the main seal pattern is united by bonding the pair of mother substrates.

8. A method of manufacturing a liquid crystal display, comprising:

preparing a pair of mother substrates;

forming a main seal pattern having a plurality of seal regions configured to surround and seal liquid crystal member and a gap maintaining member between the main seal pattern, on one of the pair of mother substrates;

forming a united configuration, in which the main seal patterns and the gap maintaining member is united by bonding the pair of mother substrates; and

cutting the bonded mother substrates at a position corresponding to the gap maintaining member.

9. A method of manufacturing a liquid crystal display, comprising:

preparing a pair of mother substrates;

forming a main seal pattern having a plurality of seal regions configured to surround and seal liquid crystal material, on either one of the pair of mother substrates;

arranging a gap maintaining member, which maintains a distance between the pair of substrates in a predetermine range, between the plurality of seal regions;

bonding of the pair of mother substrates;

thinning of at least one of the pair of mother substrates to configure ultra-thin glass; and

forming a scribe line to cut off the at least one of the pair of mother substrates, at a position corresponding to the gap maintaining member on the at least one of the pair of mother substrates.
