Embodiment 1

[0068] see figure 1 , the thin film transistor array substrate 10 may be an array substrate, and the color filter substrate 20 may be a color filter substrate. The first substrate 11 and the second substrate 21 may be one of a rigid substrate or a flexible substrate. When the first substrate 11 and the second substrate 21 are rigid substrates, the materials of the first substrate 11 and the second substrate 21 can be made of materials such as glass and quartz. When the first substrate 11 and the second substrate 21 are flexible substrates, the first substrate 11 and the second substrate 21 may be made of materials such as polyimide. In the LCD display panel 100, the substrate structure is generally set as a rigid substrate, which will not be described in detail here.

[0069] In this embodiment, the thin film transistor array substrate 10 may be a conventional array substrate or COA (Color filter on Array, a substrate with a color filter layer disposed on the array), which i...

Embodiment 2

[0113] This implementation is the same or similar to Embodiment 1, except that:

[0114] The display panel 100 further includes a color filter layer 23 in the thin film transistor array substrate 10 or the color filter substrate 20 . When the array substrate is a COA substrate, the color filter layer 23 is located in the thin film transistor array substrate 10, which can avoid the alignment error between the thin film transistor array substrate 10 and the color filter substrate 20, and improve the quality of the panel. When the array substrate is a conventional substrate, the color filter layer 23 is located in the color filter substrate 20 .

[0115] In this embodiment, the color filter substrate 20 includes a color filter layer 23 located on the second substrate 21 , and the color filter layer 23 includes at least three color resist units 231 and two adjacent color filter units 231 . The light shielding layer 232 between the color resist units 231 . One of the color resist...

Abstract

The present application provides a display panel and a display device. The display panel includes a thin film transistor array substrate and a color filter substrate disposed opposite to the thin film transistor array substrate. The thin film transistor array substrate includes a first substrate, a driving circuit layer on the first substrate, and a first common electrode layer on the driving circuit layer; the color filter substrate includes a second substrate, a driving circuit layer on the second substrate the second common electrode layer. In the present application, an impedance member is provided on the thin film transistor array substrate or color filter substrate on the display panel, and the second common electrode layer is electrically connected to the impedance member through a corresponding electrical connection member, thereby reducing the second common electrode. Therefore, when the voltage of the data line changes, the voltage recovery speed of the second common electrode layer is accelerated, and the technical problem of horizontal crosstalk in the display panel is avoided.

Description

technical field [0001] The present application relates to the field of display, and in particular, to a display panel and a display device. Background technique [0002] LCD (Liquid crystal displays, liquid crystal display) is a widely used flat panel display, which mainly realizes screen display by modulating the light field intensity of a backlight source through liquid crystal switches. [0003] In the existing LCD panel, due to the coupling capacitance between the data line and the common electrode of the color filter substrate, when the voltage of the data line changes, the voltage of the common electrode of the color filter substrate cannot be recovered quickly after the change, resulting in horizontal crosstalk on the panel. . With the increase of the panel resolution, the scanning time of each row of scanning lines is further shortened, the time for the voltage recovery of the common electrode of the color filter substrate is shorter, and the horizontal crosstalk ph...
