technical field

The utility model relates to the field of display technology, in particular to a display panel and a display device.

Background technique

Among flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, relatively low manufacturing cost and no radiation, and occupies a dominant position in the current flat panel display market. status.

At present, the display modes of TFT-LCD mainly include TN (Twisted Nematic, twisted nematic) mode, VA (Vertical Alignment, vertical orientation) mode, IPS (In-Plane-Switching, plane direction conversion) mode and AD-SDS (ADvanced Super Dimension Switch, advanced ultra-dimensional field switching technology, referred to as ADS) mode, etc. Among them, the ADS mode liquid crystal display mainly forms a multi-dimensional electric field through the electric field generated by the edge of the slit electrode in the same plane and the electric field generated between the slit electrode layer and the plate electrode layer, so that the slit electrodes in the liquid crystal cell and the electrodes are positive. All the aligned liquid crystal molecules above can be rotated, thereby improving the working efficiency of the liquid crystal and increasing the light transmission efficiency. Advanced ultra-dimensional field conversion technology can improve the picture quality of TFT-LCD products, with high resolution, high transmittance, low power consumption, wide viewing angle, high aperture ratio, low color difference, no push Mura, etc. advantage.

Taking the TFT-LCD in ADS mode as an example, the liquid crystal panel of the TFT-LCD generally includes an array substrate and a color filter substrate arranged in opposite boxes, and a liquid crystal layer located between the array substrate and the color filter substrate. The array substrate generally includes an array substrate, a group of gate scan lines and a group of data scan lines vertically intersecting the gate scan lines located on the array substrate, and adjacent gate scan lines and data scan lines define a pixel area. Each pixel area includes a gate formed on the array substrate, a gate insulating layer, an active layer, a source, a drain, a pixel electrode (ie, a plate electrode), a passivation layer, and a common electrode (ie, a narrow electrode). slit electrode), wherein the common electrode has a plurality of slit structures in the pixel area. The color filter substrate generally includes a color filter substrate and a spacer arranged on the color filter substrate. Generally speaking, N (such as N can be 24, 36, etc.) pixel areas on the array substrate correspond to the color filter A spacer on the substrate.

In actual use, parasitic capacitance will be generated between the gate, source and drain on the array substrate and the common electrode, and the existence of parasitic capacitance will greatly interfere with the display of TFT-LCD. Between the pole, source and drain and the common electrode, it acts as a medium, and the greater the thickness of the passivation layer, the smaller the parasitic capacitance. However, the material of the passivation layer is usually silicon nitride, and the thickness of silicon nitride cannot be greatly increased due to the influence of production capacity, thus resulting in a large parasitic capacitance of the TFT-LCD.

In order to reduce the parasitic capacitance of TFT-LCD, people in the industry are gradually adopting the scheme of replacing the passivation layer with an organic film layer. Since the thickness of the organic film layer is controllable, the thickness of the organic film layer can be made larger, thereby reducing the TFT - LCD parasitic capacitance. However, the adhesion between the organic film layer and the frame sealant is poor, and the adoption of this solution may result in ineffective packaging of the array substrate and the color filter substrate, which may easily lead to liquid crystal leakage.

In view of the above problems, an existing solution is: before the array substrate and the color filter substrate are boxed, hollow out the position where the organic film layer on the array substrate is opposite to the sealant, and the organic film layer is hollowed out. Fill the empty space with sealant.

The disadvantage of the above solution is that when the array substrate and the color filter substrate are boxed together, the sealing glue located between them will be squeezed to a certain extent, and the sealing glue will shrink to a certain extent under the action of the extrusion force. This is very likely to cause the thickness of the peripheral area of the display area of the liquid crystal panel to be smaller than the thickness of the display area, thereby resulting in poor thickness uniformity of the liquid crystal panel and poor product quality of the liquid crystal display.

Utility model content

The purpose of the utility model is to provide a display panel and a display device to improve the thickness uniformity of the display panel and further improve the product quality of the display device.

An embodiment of the present invention provides a display panel, including a first substrate and a second substrate arranged in a box by a sealing glue, wherein:
