Embodiment approach 1

[0037] figure 2 It is related to Embodiment 1 and is equivalent to figure 1 A detailed cross-sectional view of the sealing part 20 and the surrounding area 400 in the section A-A of FIG. figure 2 In this example, scanning signal lead-out lines 101 are formed on a first substrate 100 formed of glass. In other words, the scan signal lead-out line 101 is figure 1 A cross-section of the scan signal lead-out line 101 extending from the driver region 160 in . It should be noted that the materials of the first substrate 100 and the second substrate 200 described later can be inorganic materials such as glass, or organic materials such as polyimide.

[0038] On the scanning signal lead-out line 101 , an inorganic insulating layer 103 and an organic insulating layer 104 are formed as the first insulating layer 102 . The organic insulating layer 104 is formed thicker than the inorganic insulating layer 103 and also functions as a planarizing film. Examples of the material of the ...

Embodiment approach 2

[0073] Figure 5 It is related to Embodiment 2 and is equivalent to figure 1 A cross-sectional view of the sealing portion 20 and the surrounding area 400 in the section A-A of FIG. Hereinafter, the main points of commonality and differences from Embodiment 1 will be described.

[0074] Figure 5 Compared with Embodiment 1, in terms of forming the first protruding portion 230, the second protruding portion 232, the first spacer 210, the second spacer 220, and the fifth protruding portion 109, they are common. of. Also, the first protrusion 230 is in contact with the liquid crystal 300 . It is also common that the orientation film 106 is present in the sealing region, and that the surfaces of the first insulating layer 102 and the second insulating layer 202 in the sealing region are patterned so as to have concavo-convex portions. The advantages of having the above configuration are omitted since they are the same as those in Embodiment 1.

[0075] On the other hand, it ...

Embodiment approach 3

[0078] Figure 6 It is related to Embodiment 3 and is equivalent to figure 1 A cross-sectional view of the sealing portion 20 and the surrounding area 400 in the section A-A of FIG. Hereinafter, the main points of commonality and differences from Embodiment 1 will be described.

[0079] Figure 6 In this case, compared with Embodiment 1, the first protruding portion 230, the third protruding portion 107, the first spacer 210, and the second spacer 220 are formed, and the alignment film 106 exists in the sealing region. Words are common. Also, the first protrusion 230 is in contact with the liquid crystal 300 . The advantages of having the above configuration are omitted since they are the same as those in Embodiment 1.

[0080] On the other hand, compared with Embodiment 1, it is different in that the 2nd protrusion part 232, the 4th protrusion part 108, the 5th protrusion part 109, and the groove part 110 are not formed. In addition, the surface of the first insulating la...

Abstract

The invention discloses a display device which includes a sealant and liquid crystal sealed between a first substrate and a second substrate, and the display device includes a first projection formed either the first substrate or the second substrate and a first counterpart formed on the other substrate, wherein the sealant includes an alignment film, the first projection extends in the direction of extension of the sealant, the first projection and the first counterpart are opposed to each other, a gap is formed between the first projection and the first counterpart to locate the sealant, the first projection has a vertical dimension greater than that of the gap, and the first projection contacts the liquid crystal and overlaps an inner edge of the sealant in a plan view.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Japanese Patent Application No. 2015-213828 filed on October 30, 2015; the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a display device having two protrusions facing each other in a sealing portion. Background technique [0004] A liquid crystal display device using liquid crystals is configured by bonding a first substrate on which a plurality of pixels (having pixel electrodes, thin film transistors (TFTs), etc.) are formed and a second substrate disposed opposite to the first substrate through a sealant. Together, the liquid crystal is sealed in the sealed portion. Then, the alignment direction of the liquid crystal is controlled by a voltage to change the transmittance of light incident on each pixel, thereby forming an image. [0005] Incidentally, in today's display devices, it is s...
