Embodiment Construction

[0043] The present disclosure relates to an array substrate. In some embodiments, a first passivation layer is on a planarization layer, and the planarization layer is on a metal layer. The first protective layer has an opening, the opening is located in the display area of ​​the array substrate, and the opening penetrates the first protective layer and extends to the flat layer. Next, a conductive layer is formed on the first protection layer and fills up the opening to cover the planar layer exposed from the opening. In this way, before forming the conductive layer, an appropriate amount of water vapor can diffuse into the flat layer through the opening; and after the conductive layer is formed, excess water gas can be blocked by the conductive layer to prevent further diffusion into the flat layer. The applicant found that the electric properties of the semiconductor elements in the array substrate can be improved by controlling an appropriate amount of water vapor to ente...

Abstract

An array substrate has a display area and a circuit area. The array substrate includes a metal layer, a flat layer, a first protection layer and a conductive layer. The planarization layer is on the metal layer. The first protection layer is located on the flat layer, the first protection layer has an opening, the opening is located in the display area, and the opening exposes the flat layer without exposing the metal layer. The conductive layer is located on the first protection layer and filled into the opening to cover the flat layer exposed by the opening.

Description

technical field [0001] The present disclosure relates to an array substrate, and in particular to an array substrate capable of maintaining stable electrical properties in a display area. Background technique [0002] Many semiconductor elements are mounted on the display panel, and these semiconductor elements are especially present on the array substrate. During the manufacturing process of the display panel, the ambient atmosphere is often rich in water vapor. Once there is too much moisture in the process environment, it is easy to have an adverse effect on the electrical properties of these components. Therefore, how to maintain the stable electrical properties of the semiconductor elements in the array substrate has become one of the directions of the industry. Contents of the invention [0003] The disclosure relates to an array substrate having an opening. The flat layer is only exposed to the process environment through the opening, and an appropriate amount of...
