Abstract

A liquid crystal display device includes: a display section including a liquid crystal layer between a pair of substrates; and a frame edge section provided to a periphery section of the pair of substrates. The frame edge section includes an injection port and an injection port section, the injection port being for injection of a liquid crystal material, and the injection port section being provided between the injection port and the display section. The injection port section includes a barrier structure including a clearance, and the barrier structure being in contact with both of the pair of substrates, and a sealing material filled in a portion extending from the injection port to the barrier structure.

Claims (29)

1 . A liquid crystal display device, comprising:

a display section including a liquid crystal layer between a pair of substrates; and

a frame edge section provided to a periphery section of the pair of substrates, wherein

the frame edge section includes an injection port and an injection port section, the injection port being for injection of a liquid crystal material, and the injection port section being provided between the injection port and the display section, and

the injection port section includes

a barrier structure including a clearance, and the barrier structure being in contact with both of the pair of substrates, and

a sealing material filled in a portion extending from the injection port to the barrier structure.

2 . The liquid crystal display device according to claim 1 , wherein

the barrier structure includes

a wall provided to one or both of the pair of substrates, and the wall extending in a direction intersecting with a direction from which the sealing material comes, and

a plurality of pillars provided on the wall.

3 . The liquid crystal display device according to claim 2 , further comprising

an inclined section at an outlet of the clearance.

4 . The liquid crystal display device according to claim 2 , wherein

the barrier structure is provided at two or more positions where distances from the injection port are different.

5 . The liquid crystal display device according to claim 1 , wherein

the barrier structure has a plurality of walls between the pair of substrates in a direction not vertical to a direction from which the sealing material comes.

6 . The liquid crystal display device according to claim 1 , wherein

the barrier structure is configured by a layer the same as other layers configuring the display section.

7 . A method of manufacturing a liquid crystal display device, the liquid crystal display device including a display section including a liquid crystal layer between a pair of substrates, and a frame edge section provided to a periphery section of the pair of substrates, and the frame edge section including an injection port and an injection port section, the injection port being for injection of a liquid crystal material, and the injection port section being provided between the injection port and the display section,

the method comprising:

forming a barrier structure to the injection port section, and the barrier structure including a clearance and being in contact with both of the pair of substrates; and

filling a sealing material in a portion extending from the injection port to the barrier structure.

8 . The method according to claim 7 , wherein

the barrier structure is formed at the same time as other layers configuring the display section.

9 . The method according to claim 8 , wherein

the barrier structure is formed in a multi-layer structure including a plurality of layers, and the plurality of layers are allocated to both of the pair of substrates.

10 . The method according to claim 8 , wherein

the barrier structure is entirely provided to either one of the pair of substrates.
