Problems solved by technology

Narrow frame design is a development trend of liquid crystal displays. When the frame of the display becomes narrower, the distance between the frame glue and the display area will decrease accordingly, and the impurity ions in the frame glue will diffuse into the display area. Large, impurity ions may affect the deflection of liquid crystal, thereby affecting the normal display of the display

Abstract

The invention discloses a display panel and a display device, which relate to the field of display technology and include a first substrate and a second substrate opposite to each other; the first substrate includes a first substrate, a first potential line and a second potential line, and is located at a first potential line and the second potential line face at least one third potential line on the side of the second substrate, and the third potential line is isolated from the first potential line and the second potential line by the first insulating layer; In the display area, the first insulating layer includes a first groove and a second groove; the first potential line receives a positive voltage, the second potential line receives a negative voltage, and the third potential line receives a reference voltage; the first potential line and the third The potential line forms the first electric field in the first groove, and the second potential line and the third potential line form the second electric field in the second groove; the frame glue forms the first electric field between the edge of the frame glue near the display area and the display area. an interval. In this way, it is beneficial to reduce the amount of impurity ions diffused from the sealant to the display area.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] Liquid crystal display is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. [0003] The working principle of liquid crystal display: Liquid crystal is a special substance between solid and liquid. It is an organic compound, which is liquid under normal conditions, but its molecular arrangement is as regular as solid crystal, so it is named liquid crystal. , Its other special property is that if an electric field is applied to the liquid crystal, its molecular arrangement will be changed. At this time, if it is equipped with a polarizer, it will have ...
