Problems solved by technology

[0005] However, although the metal oxide thin film transistor has better electrical properties, it is easily affected by the moisture and oxygen in the environment, resulting in poor reliability of the display panel; in addition, in the application of high-resolution products, in order to improve The aperture ratio of the display panel will also introduce the material of the organic flat layer, such as perfluoroalkoxy vinyl ether copolymer (Polyfluoroalkoxy, PFA). Since the ability of organic materials to block water vapor is poorer than that of inorganic materials, it may It will absorb water vapor, which will affect the reliability of thin film transistors and other components in the display area

Embodiment Construction

[0025] The display panel according to the preferred embodiment of the present invention will be described below with reference to the related drawings, wherein the same elements will be described with the same reference symbols.

[0026] 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 in the process of the display panel, but the oxide thin film transistors are easily affected by the moisture and oxygen in the environment , 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 characteristics of the thin film transistor to shift, thereby reducing the reliability of the display panel.

[0027] Please refer to figure 1 As shown, it is a schematic diagram of the relationship between water absorption rate and time of an organic ma...

Abstract

A display panel comprises a first substrate, a second substrate and an organic planarization layer. The first substrate has an active area and a non-active area disposed adjacent to the active area. The second substrate is disposed opposite the first substrate. The organic planarization layer is disposed on the first substrate facing the second substrate and includes at least a first through portion which is disposed in the non-active area and exposes a film layer under the organic planarization layer.

Description

technical field [0001] The present invention relates to a display panel, in particular to a display panel with high reliability. Background technique [0002] With the advancement of technology, flat display panels have been widely used in various fields. Due to their superior characteristics such as 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 of of 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, a liquid crystal display panel in the prior art includes a thin film transistor substrate and a color filter substrate, which are disposed opposite to each other. Wherein, the thin film transistor substrate has a plurality of thin film transistors and a plurality of pixel electrodes disposed on a substrate. In the process, a throug...
