Embodiment 1

[0039] see Figure 7 , Figure 7 It is a schematic diagram of the spatial light path entering the channel region of the array substrate. exist Figure 7 After the light shown below enters, the cell gap of the display panel (such as Figure 7 The space between the black matrix layer above the first passivation layer 6 and below the second substrate 12) has light entering, although the channel region can be affected by the first light shielding layer 2 and the black matrix layer below the second substrate 12. For protection, but the light will be diffusely reflected in the cell, and the diffusely reflected light can still enter the channel area (the area shown by the inverted trapezoid in the center of the figure), such as Figure 7 As shown, the light entering the channel region increases the photo-generated carriers in the channel region of the TFT device, which in turn leads to an increase in the leakage current. Working, abnormally working liquid crystals may often cause...

Embodiment 2

[0050] Based on the same inventive concept as Embodiment 1, this embodiment provides a display panel, the display panel includes an array substrate of any structural form in Embodiment 1, and the specific structure of the array substrate is as described in Embodiment 1, This embodiment will not be repeated here, such as Figure 1-7 As shown, the display panel may further include a second substrate 12 disposed above the protective layer 3, and a second color resist layer 13 is disposed under the second substrate 12. In this embodiment, the second color resist layer 13 may be red At least one color resist among color resists, green resists, or blue resists. When this embodiment is implemented, the second color resist layer 13 on the left can be green resists, red resists, or blue resists, and the second color resist on the right The resist layer 13 may be a red resist or a green resist or a blue group. In specific implementation, the second substrate 12 can often be a CF (color...

Embodiment 3

[0052] Based on the same inventive concept as the first embodiment, this embodiment provides a liquid crystal display device, the liquid crystal display device includes the display panel in the second embodiment or the array substrate in the first embodiment, and in a specific application, the liquid crystal display device The device can be a display screen of a smartphone, tablet computer, notebook computer, smart bracelet, smart watch, smart glasses, smart helmet, desktop computer, smart TV or digital camera, etc. on electronic devices.

Abstract

The invention discloses an array substrate, a display panel and a liquid crystal display device. The array substrate comprises a first substrate and a thin film transistor arranged over the first substrate, the thin film transistor is provided with a channel region, a first shading layer is arranged between the channel region and the first substrate, and a protective layer used for reducing the number of photo-generated carriers in the channel region is arranged over the channel region; the display panel comprises the array substrate, and the liquid crystal display device comprises the displaypanel. The invention can provide a design scheme for improving image persistence of a display. The number of the photon-generated carriers in the channel region is greatly reduced by absorbing photoelectrons or reducing the transmissible path of light; therefore, the liquid crystal polarization effect can be obviously reduced, the image residue is improved, the problem of image residue caused byphoton-generated carriers of an existing display panel is thoroughly solved, the quality of the display panel is remarkably improved, and the user experience is good.

Description

technical field [0001] The present invention relates to the field of display technology, more specifically, the present invention is an array substrate, a display panel and a liquid crystal display device. Background technique [0002] At present, most of the liquid crystal displays on the market are backlight liquid crystal displays. The backlight liquid crystal display includes a liquid crystal display panel and a backlight module (backlight module), and liquid crystal molecules are often placed between two parallel glass substrates, and the two pieces There are many small wires arranged in the glass substrate, and the liquid crystal molecules are controlled to change the wires by whether the electricity is on or not, so as to refract the light from the backlight module and generate a corresponding picture; the processing technology generally includes: front-end array (array) process, middle-end The cell process and the back-end module assembly process, among which, the ab...
