Abstract
A touch panel including a substrate, an insulating layer, touch electrode blocks, and electrode lines. The touch electrode blocks include an array of first type touch electrode blocks having a regular shape and a second type touch electrode block having an irregular shape. Ones of the first type touch electrode blocks are electrically connected to respective ones of the electrode lines by respective X first contact vias extending through the insulating layer, and the respective X first contact vias are arranged along a straight line in a column direction. The second type touch electrode block is electrically connected to a first corresponding one of the electrode lines by Y second contact vias extending through the insulating layer, and the Y second contact vias are arranged along at least one straight line in the column direction. X and Y are natural numbers, and 0.75×X≤Y≤1.25×X.
