Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] In order to avoid the angular step difference problem of the color filter substrate in the manufacturing process of the existing display device, an embodiment of the present invention provides a display device, the display device includes an array substrate, a color filter substrate, and an array substrate and the The liquid crystal layer between the color filter substrates. Wherein, the color filter substrate does not include a black matrix; the gate insulating layer of the array substrate is made of black insulating material, and the gate insulating layer has an opening exposing the pixel area, so that the gate insulating layer simultaneously functions as a black The role of the matrix. Specifically, the display device may be a liquid crys...

Abstract

The invention provides an array substrate, a production method of the array substrate and a display device and belongs to the field of liquid crystal display. A gate insulating layer of the array substrate is made of black insulating material. The gate insulating layer is provided with an opening for exposing a pixel region. By the array substrate, quality of display frames is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an array substrate, a manufacturing method of the array substrate and a display device. Background technique [0002] The liquid crystal display includes pixel units designed in a matrix form, and a driving circuit for driving these pixel units. The liquid crystal molecules are deflected through the change of the electric field in the liquid crystal cell to achieve the display effect. [0003] Most of the existing liquid crystal display devices adopt the traditional black matrix manufacturing technology, that is, in order to avoid the problem of light leakage, the black matrix is ​​fabricated on the color filter substrate, and the red color resistance R, the green color resistance G and the blue color resistance B are respectively overlapped. (Over Lap) is connected with the black matrix. Such a structure will inevitably bring about the problem of angular difference, which ...
