Embodiment 1

[0033] Such as figure 1 and figure 2 As shown, the liquid crystal panel provided by the embodiment of the present invention includes an array substrate 10 and a color filter substrate 20 . Components such as common electrode lines 1 are disposed on the array substrate 10 , and components such as a color filter layer (not shown in the figure), black matrix 2 , and common electrodes 3 are disposed on the color filter substrate 20 . Both the common electrode line 1 and the common electrode 2 are supplied with voltage by a power supply circuit (not shown in the figure) in the circuit board 4 , and the power supply circuit provides equal voltages to the common electrode line 1 and the common electrode 3 .

[0034] The power supply circuit is connected to the common electrode line 1 through the first wiring 51 on the array substrate 10 . On the other hand, the power supply circuit is connected to the common electrode 3 on the color filter substrate 20 through the second wiring 52...

Embodiment 2

[0047] This embodiment is basically the same as Embodiment 1, the difference is that, as image 3 As shown, the second wiring and the conductive gold ball in the first embodiment are omitted in this embodiment.

[0048] Because the power supply circuit in the circuit board 4 provides the same voltage for the common electrode line 1 and the common electrode 3, so in this embodiment, the power supply circuit provides voltage for the common electrode line 1 on the array substrate 10 through the first wiring 51 , and then provide voltage to the common electrode 3 on the color filter substrate 20 through the common electrode line 1 and the conductive connector. Therefore, the second wiring and the conductive gold ball in Embodiment 1 can be omitted without affecting the stability of the voltage on the common electrode 3, thereby reducing the wiring in the edge area 101 of the array substrate 10 and making the liquid crystal panel It can have a narrower frame, and the LCD panel can...

Embodiment 3

[0050] An embodiment of the present invention provides a display device, which may be a liquid crystal television, a liquid crystal display, a mobile phone, a tablet computer, and the like. The display device includes the liquid crystal panel provided in Embodiment 1 or Embodiment 2 above, and components such as a backlight module.

Abstract

The invention discloses a liquid crystal panel and a display device, belongs to the technical field of display, and solves the technical problem that the display effect of the liquid crystal panel is affected because the voltage of a public electrode line is instable. The liquid crystal panel comprises an array base plate and a color film base plate; the public electrode line is arranged on the array base plate; a public electrode is arranged on the color film base plate; the public electrode line is electrically connected with a public electrode via a conductive connecting part. The liquid crystal panel disclosed by the invention can be applied to display devices, including liquid crystal TVs, liquid crystal displays, cell phones, tablet computers and the like.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal panel and a display device. Background technique [0002] With the development of display technology, a liquid crystal display (LCD) has become the most common flat panel display device. [0003] A liquid crystal display usually includes an array substrate and a color filter substrate. Each pixel unit is divided by criss-cross gate lines and data lines on the substrate, and each pixel unit is provided with a thin film transistor (TFT) and a pixel electrode. When the thin film transistor is turned on, the electrical signal on the data line can be transmitted to the pixel electrode through the thin film transistor, and a liquid crystal capacitance (Clc) will be formed between the pixel electrode and the common electrode on the color filter substrate. In addition, a common electrode line is provided on the array substrate, and a storage capacitor (Cst) is formed ...
