Problems solved by technology
However, if water vapor has been inhaled during the process of the organic planarization layer, after the subsequent inorganic insulating layer is covered, the water vapor may be sealed by the inorganic insulating layer and cannot be dissipated, which will affect the device characteristics of the display panel and reduce product reliability.

Embodiment Construction
[0027] A display panel and a display device according to preferred embodiments of the present invention will be described below with reference to related drawings, wherein the same elements will be described with the same reference symbols.
[0028] In order to reduce the power consumption of the display panel, increase the operating frequency and increase the aperture ratio, oxide thin film transistors and organic planarization layer materials are introduced into the display panel process, but oxide thin film transistors are easily affected by environmental moisture and oxygen. , and the water vapor adsorption capacity of the organic material is also greater than that of the inorganic material, so it is easy to cause the characteristic deviation of the thin film transistor, thereby reducing the reliability of the display panel.
[0029] Please refer to figure 1 As shown, it is a schematic diagram of the relationship between water absorption rate (waterabsorption rate) and tim...

The invention provides a display panel and a display device. The display panel is provided with a display area and a peripheral area adjacent to the display area and comprises a first substrate, a second substrate, a first insulation layer, an organic layer and a second insulation layer. The second substrate is opposite to the first substrate. The first insulation layer is arranged on the side, facing the second substrate, of the first substrate. The first insulation layer is covered with the organic layer. The organic layer is covered with the second insulation layer. At least one first penetrating portion is arranged and located on the peripheral area, and the first penetrating portions are exposed to the organic layer. When water vapor permeates into the organic layer from the outside in the process, the step of dewatering can be carried out before the subsequent panel assembling process to enable the water vapor to dissipate through the first penetrating portions, and the water vapor content of the organic layer is reduced. Therefore, the degree of the organic layer of adsorbing the water vapor can be effectively decreased through the display panel completed through the subsequent process, and then the element reliability of the display panel is improved.
Description
technical field [0001] The present invention relates to a display panel and a display device, in particular to a display panel and a display device with high reliability. Background technique [0002] With the advancement of technology, flat-panel display panels have been widely used in various fields. Due to their superior characteristics such as light and thin body, low power consumption and no radiation, they have gradually replaced traditional cathode ray tube display devices and have been applied to many types. Electronic products such as mobile phones, portable multimedia devices, notebook computers, LCD TVs and LCD screens, etc. [0003] Taking a liquid crystal display panel as an example, an existing liquid crystal display panel includes a thin film transistor substrate and a color filter substrate, which are arranged opposite to each other. Wherein, the TFT substrate has a plurality of TFTs and a plurality of pixel electrodes disposed on a substrate, the TFTs can b...
