The present invention relates to a liquid crystal display device and a sealant applicator for the liquid crystal display device.

The liquid crystal display is one of the flat panel display devices most widely used at present, and includes two display panels on which an electric field generating electrode is formed and a liquid crystal layer interposed therebetween.

The liquid crystal display may further include a thin film transistor connected to one of the field generating electrodes and various signal lines transferring a signal thereto. Such electric field generating electrodes, thin film transistors, signal lines, etc. are composed of a plurality of conductor layers, and these conductor layers are insulated with an inorganic or organic insulating film. In recent years, the use of organic films has been increasing, particularly in the case of transflective liquid crystal displays.

When making a liquid crystal display device, two display panels are bonded together by a sealing material. The seal is mainly made of an ultraviolet (UV) curable or thermoset material.

The sealing material is in contact with the liquid crystal layer, and if there is an organic film, it may also be in contact with the organic film. The organic film is also in contact with the liquid crystal layer.

However, impurities such as ions may come out of the sealing material in the process of curing the sealing material, and may diffuse into the organic film or the liquid crystal in contact with the organic film. In this case, the reaction speed of the liquid crystal may be slowed, and an afterimage may occur or the edges of the display panel may be stained. In addition, in order for the display panels to be firmly coupled, the adhesive force between the organic layer and the sealing material needs to be strong.

The technical problem of the present invention is to solve such a problem, it is possible to prevent a poor contact between the sealing material and the organic film, and to prevent a liquid crystal failure due to impurities during sealing.

According to an exemplary embodiment, a liquid crystal display device includes a first display panel including an organic layer, a second display panel facing the first display panel, a liquid crystal layer positioned between the first display panel and the second display panel, and A sealing material is disposed between the first display panel and the second display panel and is in contact with the organic layer. The sealing material includes a first member spaced apart from the liquid crystal layer and a second member contacting the liquid crystal layer.

The sealant may further include a third member positioned opposite to the second member with respect to the first member.

The material of the third member may be the same as the material of the second member.

The first member may be made of an epoxy resin to which silane is added.

The second member may be made of an epoxy resin to which no silane is added.

The first display panel may further include a pixel electrode formed on the organic layer and a thin film transistor formed under the organic layer.

The pixel electrode may include a transparent electrode and a reflective electrode formed on a portion of the transparent electrode.

As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Like parts are designated by like reference numerals throughout the specification. When a part of a layer, film, region, plate, etc. is said to be "on" another part, this includes not only the other part being "right over" but also another part in the middle. On the contrary, when a part is "just above" another part, there is no other part in the middle.

Now, a thin film transistor array panel according to an exemplary embodiment of the present invention, a liquid crystal display including the same, and a manufacturing method thereof will be described in detail with reference to the accompanying drawings.

First, a thin film transistor array panel and a liquid crystal display according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

1 is a plan view of a thin film transistor array panel according to an exemplary embodiment of the present invention, and FIG. 2 is a cross-sectional view of the liquid crystal display including the thin film transistor array panel of FIG. 1 taken along line II-II.

Referring to FIG. 2, the liquid crystal display according to the present exemplary embodiment includes a thin film transistor array panel 100, a common electrode panel 200 facing the thin film transistor panel, and a sealing material 310 formed between the two display panels 100 and 200. The liquid crystal layer 3 is included.

As illustrated in FIG. 1, the thin film transistor array panel 100 includes a lower substrate 110 and is divided into a display area DA and a peripheral area PA. In the display area DA, a plurality of conductor layers including a plurality of pixel electrodes 191, a plurality of thin film transistors (not shown), a plurality of signal lines (not shown), and the like are formed, and an alignment layer 11 thereon. ) Is formed. These conductor layers are insulated with an inorganic or organic insulating film or the like. In particular, an organic film 187 is formed as a protective film under the pixel electrode 191 and above the thin film transistor. The organic layer 187 covers not only the display area DA but also the peripheral area PA.

The peripheral area PA surrounds the display area DA, and an end portion of the signal line extends to the peripheral area PA.

As illustrated in FIG. 2, the common electrode display panel 200 includes an upper substrate 210, a light blocking member 220, an overcoat 250, a common electrode 270, an alignment layer 21, and the like disposed thereon. .

The light blocking member 220 has an opening facing the pixel electrode 191.

The sealing material 310 is positioned on the organic layer 187 of the peripheral area PA, surrounds the display area DA, and crosses the signal line. The encapsulant 310 seals the liquid crystal layer 3 between the thin film transistor array panel 100 and the common electrode display panel 200, and bonds the thin film transistor array panel 100 and the common electrode display panel 200 to each other.

Referring to FIG. 2, the sealing material 310 includes a first member 311, a second member 312, and a third member 313.

The first member 311 may be made of a material having good contact force with the organic layer 187.

The second member 312 does not discharge impurities such as ions to the organic film 187 or the liquid crystal layer 3, and impurities generated in the first member 312 are applied to the organic film 187 or the liquid crystal layer 3. It can be made of a material that can prevent it from diffusing. The third member 313 may be made of the same material as the second member 312.

Examples of the material forming the first and second members 311 and 312 include a UV curable or thermosetting material such as an epoxy resin, and the first member 311 may be formed of a coupling agent such as silane. It is good to add it, and it is good that the 2nd member 312 does not add the coupling agent (coupling agent). The binder increases the bonding force between the sealing material 310 and the organic film 187, but in the sealing process, dehydration reaction or ionic impurities escape from the sealing material 310 to the liquid crystal layer 3 or the organic film 187. This can cause symptoms.

In this way, it is possible to reduce the amount of impurities generated from the sealing material 310 to be injected into the organic layer 187 or the liquid crystal layer 3. As a result, afterimages and displays generated as the response speed of the liquid crystal molecules decreases due to the impurities. Smudge at the edge of the area DA can be reduced.
