Abstract

The invention discloses a display panel and a display device. The display panel comprises a first substrate, a second substrate, a grind line extending in a first direction, and a touch line extending in a second direction, wherein the touch line is composed of a bar-shaped extending unit and a lateral protrusion unit formed on the bar-shaped extending unit; in the direction perpendicular to the plane where the first substrate is arranged, the projection of the lateral protrusion unit has no overlap with that of the grid line; one side of the second substrate, which is close to the first substrate, is provided with a black matrix, and in the direction perpendicular to the plane where the first substrate is arranged, the projection of the black matrix covers that of the lateral protrusion unit; the first direction and the second direction are crossed. According to the technical scheme of the display panel, the coupling capacitance between the touch line and the grid line can be minimized, and further influence of the coupling capacitance onto the display performance of the display panel can be reduced to the minimum degree.

Description

【Technical field】 [0001] The present invention relates to the technical field of microelectronics, in particular to a display panel and a display device. 【Background technique】 [0002] The display panel includes a first substrate and a second substrate. The first substrate is arranged opposite to the second substrate. On the first substrate, a plurality of gate lines, a plurality of data lines and a plurality of A plurality of touch lines, wherein, a plurality of data lines and a plurality of gate lines intersect to define a plurality of sub-pixel units, the extension directions of the plurality of data lines and the plurality of touch lines are the same, and the plurality of gate lines communicate with the gate driving circuit, and The touch wires are connected to the IC driving circuit. Generally, the touch wire lugs on the touch wires are arranged on the gate wires, that is to say, in the direction perpendicular to the plane where the first substrate is located, the touc...
