That is, one end of the first side wall 31 and the second side wall 12 is connected to one end of the second bottom wall 32 and the fourth side wall 14 is less than the first bottom wall 31.

[0121] Wherein, the γ2 may be equal to or not equal to the γ1. In the present embodiment, the γ2 is equal to the γ1.

[0122] Among them, since the first waist portion 101 is asymmetrical with the second waist 102 such that the first electrode 600 has a first set of inclination angles and a second set of inclination angles, not only the inclination of the first electrode 600 can be increased. The selection range is also capable of avoiding the mutual interference zone, reducing the dark domain, and lifting the transmittance.

[0123] Of course, the improvements involved in the sixth embodiment are also applicable to the first embodiment, the third embodiment, fourth embodiment, and fifth embodiments.

[0125] In the present application, in an alternative embodiment, the cavity 102 is a fish shape.

[0126] See Figure 14 The eighth embodiment of the present application also provides a first electrode 800, and the structure of the first electrode 800 is similar to the structure of the first electrode 700, which is different from the first electrode 800.

At this time, the θ1 may be equal to or eliminating θ2, and the θ3 is equal to or at least at the θ4.

[0130] Among them, since the first waist 101 is asymmetrical with the second waist 102 such that the first electrode 800 has a first set of inclination angles and a second set of inclination angles, not only the inclination of the first electrode 800 The selection range is also capable of avoiding the mutual interference zone, reducing the dark domain, and lifting the transmittance.

[0131] Of course, the present application also provides the same first electrode (common electrode) having the inner wall shape of the cavity and the first embodiment, the third embodiment, fourth embodiment, and the first electrode of the first electrode of the fifth embodiment, and then This will be described later.

[0132] The array substrate, liquid crystal display panel, and display device provided herein, 1) design the shape of the first electrode to have a first waist (composed of the first side wall, the second side wall and the first bottom wall) and the second The waist (consisting of the third side wall, the fourth side wall, and the second bottom wall), and the shortest distance of the first waist to the second waist is smaller than the first side wall away from the second side wall. One end to the third side wall away from the distance from one end of the fourth side wall and is smaller than the second side wall away from the first side wall to the fourth side wall away from the third side wall. The distance of one end, thereby obtaining a fish-shaped electrode, by changing the shape of the first electrode can reduce the invalid electric field component and the electric field disorder, thereby reducing the area of ​​the display dark zone, thereby lifting the penetration rate while taking care of the response time. 2) The first side wall is adjacent to the second side wall of the second side wall adjacent the end of the fourth side wall with the angle of the fourth side wall with the first direction is greater than 0 °. Alternately, the first waist is asymmetrically asymmetrical, not only, it can increase the inclination of the first electrode, but also avoid the mutual interference area of ​​the liquid crystal rotation, reduce the dark domain, and improve the transmittance. ; 3) Since the response time is reduced as the electrode is increasing, the penetration ratio is increased with the electrode increasing angle, and therefore, the value of the inclination of the first electrode is set at 3 ° -35 °. Between, it is possible to improve the penetration of the display panel, and it can have a good response time to meet the requirements of the VR display device. 4) When the first electrode provided by the present application, the waist of the electrode shrinks, Thereby, the distance between adjacent two electrodes is increased, thereby reducing the risk of crosslinking in the exposure development process.
