Display panel and display device

A display device, comprising a display panel, wherein the display panel comprising:

• an array substrate and an opposite substrate arranged opposite to each other, wherein the array substrate comprises a box alignment area facing the opposite substrate, and a circuit test area located on a side of the box alignment area;
• the opposite substrate comprises a base substrate, and a conductive black matrix arranged on a side of the base substrate facing the array substrate;
• the display panel further comprises an electrostatic discharging layer electrically connected respectively with the conductive black matrix, and a ground (GND) wire in the circuit test area;
• and
• the conductive black matrix has an area in contact with the electrostatic discharging layer, and is provided with a thickened area in at least the area in contact with the electrostatic discharging layer;
• and a thickness of the thickened area of the conductive black matrix is greater than a thickness of other areas of the conductive black matrix.
