Problems solved by technology

[0004] However, the narrower the frame of the narrow-frame display panel, the smaller the shading BM (Black Matrix) of the frame needs to be reduced, which will cause the black matrix to be easily peeled off from the glass substrate, resulting in a decrease in the contrast of the display and insufficient shading effect, etc. Phenomenon

Embodiment 1

[0033] Usually, the liquid crystal display panel consists of a color filter substrate (CF, Color Filter), a thin film transistor substrate (TFT, ThinFilm Transistor), a liquid crystal (LC, Liquid Crystal) sandwiched between the color filter substrate and the thin film transistor substrate, and a sealant frame (Sealant )composition. Among them, the thickness of the liquid crystal layer, that is, the thickness of the cell (Cell Gap) is mainly controlled by the height of the spacer (Post Spacer, PS) arranged between the array substrate and the color filter substrate, and the thickness of the liquid crystal layer has a great influence on the structural parameters of the liquid crystal display device. and display quality have an important impact, usually the spacers are formed on the side of the color filter substrate. The color filter substrate generally includes a substrate, a light-shielding unit (such as a black matrix) formed on the substrate, and a color filter layer. The lig...

Embodiment 2

[0037] In order to better describe the functional substrate of the first embodiment, this embodiment specifically describes the specific structure of the liquid crystal substrate on the basis of the foregoing embodiments.

[0038] In the current manufacturing process of color substrates, the light-shielding unit (such as black matrix) is generally in direct contact with the smooth glass substrate by coating. During the peeling test in the panel reliability test, the black matrix and the glass on which it is located The substrates will be separated under the peeling force, which indicates that the interface adhesion between the black matrix and the glass substrate on which it is located is insufficient. Therefore, in order to solve the problem that the black matrix is ​​easy to peel off from the glass substrate, please refer to figure 2 In this embodiment, the coupling layer 103 is selected as a silane coupling agent (Y-R-Si(OR) 3), and Y-R- is recorded as X, the silaneoxy gr...

Embodiment 3

[0046] An embodiment of the present invention further provides a liquid crystal display panel, and the liquid crystal display panel of this embodiment will be described in detail on the basis of the foregoing embodiments.

[0047] See Figure 5 , Figure 5 It is a schematic structural diagram of a liquid crystal display panel provided by an embodiment of the present invention. The liquid crystal display panel includes a functional substrate 10, a second substrate 20, and a liquid crystal layer 30, wherein the functional substrate 10 and the second substrate 20 are oppositely arranged, and the liquid crystal layer 30 is arranged between the functional substrate 10 and the second substrate 20, that is, the first A substrate 101 is disposed opposite to the second substrate 20 , and the liquid crystal layer 30 and the light-shielding unit 102 are disposed between the functional substrate 10 and the second substrate 20 . The TFT-LCD panel can be regarded as a layer of liquid crys...

Abstract

The invention discloses a functional substrate, a liquid crystal display panel and a display. The functional substrate comprises a first substrate (101),a plurality of shading units (102) and a coupling layer (103), wherein the plurality of shading units (102) are arranged at one side of the first substrate (101); and the coupling layer (103) is arranged between the first substrate (101) and the shading units (102). According to the functional substrate, the coupling layer is additionally arranged between the first substrate and the shading units, so that bonding is generated between the coupling layer and the first substrate and between the coupling layer and the shading units, the adhesive force between the first substrate and the shading units is increased, and the problem that the shading units are easily stripped from the first substrate is avoided, so that the problem that the contrast of the display is reduced due to the fact that the shading units are stripped from the first substrate is avoided, and meanwhile, the shading effect is guaranteed.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a functional substrate, a liquid crystal display panel and a display. Background technique [0002] With the development of information technology, people's demand for display devices has grown rapidly. In order to meet this demand, display devices represented by liquid crystal display devices (LCD, Liquid Crystal Display), plasma displays (PDP, Plasma Display Panel), and organic light emitting display devices (OLED, Organic Light Emitting Diode) have been rapidly developed. develop. Among flat panel display devices, liquid crystal display devices have been widely used in various aspects of daily life due to their advantages of low weight, small size, and low energy consumption, such as televisions, monitors, computer screens, notebook computers , personal digital assistants and mobile phones and other electronic products. [0003] Along with the development trend...
