[0001] This utility model relates to the field of display panel technology, and more specifically, to a liquid crystal display panel. Background Technology
[0002] Liquid crystal display (LCD) panels are among the most widely used display devices in modern display technology. They mainly utilize the optical properties of liquid crystals to control the transmission of light, thereby displaying images.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a liquid crystal display panel, including a substrate 1, a first substrate and a second substrate. The first substrate includes a resist layer 4, which is located above the substrate 1. A pixel electrode layer 5 is fixedly connected to the top of the resist layer 4, and an insertion groove 6 is formed at the top of the pixel electrode layer 5.
[0023] The second substrate includes a common electrode layer 8 above the pixel electrode layer 5, and an insertion layer 7 is provided at the bottom end of the common electrode layer 8. The insertion layer 7 is inserted into the inner cavity of the insertion groove 6.
[0024] The insertion slot 6 at the top of the pixel electrode layer 5 allows the bottom end of the common electrode layer 8 to be inserted into the cavity of the insertion slot 6 via the insertion layer 7. This improves the stability of the connection between the common electrode layer 8 and the pixel electrode layer 5, preventing separation between the insertion layer 7 and the pixel electrode layer 5. Furthermore, the insertion layer 7 is conductive, ensuring both the stability of the connection between the pixel electrode layer 5 and the common electrode layer 8 and the normal connection between them, thus enabling normal use.
[0025] The substrate 1 has an outer side plate 11 on its outer side. The front and rear sides of the outer side plate 11 are fixedly connected with side strips 12, the left and right sides of the outer side plate 11 are fixedly connected with side strips 13, and the bottom end of the outer side plate 11 is fixedly connected with a bottom strip 14.
[0026] By embedding this application within the monitor housing, the bottom of the outer panel 11 is supported by the bottom strip 14, and the sides of the outer panel 11 are supported by the side strips 12 and 13. This avoids direct contact between the outer panel 11 and the monitor housing. Furthermore, the gap between the outer panel 11 and the monitor housing allows air to pass through during heat dissipation, thus improving heat dissipation efficiency.
[0027] The first substrate further includes a gate insulating layer 2, which is fixedly connected above the substrate 1, and a passivation layer 3 is fixedly connected to the top of the gate insulating layer 2.
[0028] The gate insulating layer 2 effectively prevents current from passing directly, thus avoiding short circuits. Although the gate insulating layer 2 is an insulator, it allows an electric field to pass through. The electric field will pass through the insulating layer of the gate insulating layer 2 and act on the semiconductor layer. Thus, the conductivity of the gate insulating layer 2 can be used to achieve switching control of the current. In addition, the gate insulating layer 2 can also block alkali metal ions from the outside, thereby effectively preventing these ions from diffusing into the semiconductor layer and improving the performance of the panel.
[0029] Furthermore, by setting the passivation layer 3, it is possible to effectively prevent contamination by moisture, humidity and impurities, avoid damage to the physical and electrical properties of the device, and also prevent short circuits between the upper and lower layers.
[0030] Among them, the resist layer 4 is fixedly connected above the passivation layer 3, and the pixel electrode layer 5 is located at the top of the first substrate.
[0031] The main function of the resist layer 4 is to filter light of a specific wavelength, thereby enabling the display of the three primary colors of red, green and blue. Furthermore, by controlling the brightness of the backlight and the arrangement of liquid crystal molecules, color mixing and display can be achieved. Then, by setting the pixel electrode layer 5, voltage is applied to control the arrangement direction of the liquid crystal molecules, and these liquid crystal molecules can rearrange according to the direction of the electric field. This arrangement also changes the light transmittance, thereby realizing the display of the image.
[0032] Among them, a fixing layer 9 is fixedly connected to the top of the common electrode layer 8;
[0033] An electric field is formed by setting the common electrode layer 8. When a voltage is applied between the common electrode and the pixel electrode, the electric field acts on the liquid crystal molecules, thereby changing the amount of light transmitted. Furthermore, the setting of the common electrode layer 8 can also optimize the display effect and reduce problems such as flicker and image retention.
[0034] The top of the fixed layer 9 is fixedly connected to the top substrate 10, and the substrate 1 is fixedly connected below the gate insulating layer 2.
[0035] By providing physical support for the entire application, the overall stability and integrity are ensured, and the substrate 1, top substrate 10, and outer side plate 11 prevent external moisture or impurities from contaminating the multilayer panel.
[0036] Among them, side strip 12, side strip 2, and bottom strip 14 are all composed of multiple rectangular strips, and the outer side plate 11 is rectangular;
[0037] The arrangement of side strip 12, side strip 2 13, and bottom strip 14 creates a gap between the outer side panel 11 and the monitor casing, allowing for the smooth passage of heat dissipation air and significantly improving heat dissipation performance.
[0038] The working principle and usage process of this utility model are as follows: The gate insulating layer 2, passivation layer 3, resistive layer 4 and pixel electrode layer 5 are supported by the substrate 1 to form a first substrate. Then, the fixing layer 9 and common electrode layer 8 are supported by the top substrate 10 to form a second substrate. Then, the insertion layer 7 at the bottom of the common electrode layer 8 is inserted into the cavity of the insertion groove 6 of the pixel electrode layer 5, thereby improving the stability of the connection between the first substrate and the second substrate.
[0039] After installation, the outer side plate 11 is installed on the outside of the first substrate and the second substrate. Then, the outer side plate 11 is installed in the display housing. At this time, the four sides of the outer side plate 11 are protected by the side strip 12 and the side strip 2 13, and the bottom of the outer side plate 11 is protected by the bottom strip 14.
