Abstract
A touch sensing unit includes first sensing electrodes (FSEs), second sensing electrodes SSEs, first signal lines (FSLs), second signal lines (SSLs), and connection lines (CLs). The FSEs extend in a first direction (D1) and are arranged in a second direction (D2) intersecting the D1. The SSEs extend in the D2 and are arranged in the D1. The FSLs are connected to the FSEs, respectively. The SSLs are connected to the SSEs, respectively. The CLs are connected to the FSEs via the FSLs. The FSEs are grouped into blocks. Each of the blocks includes p FSEs of the FSEs, and p FSLs connected to the p FSEs, respectively, “p” being a natural number greater than one. A k-th CL of the CLs is connected to one of the FSEs of each of the blocks, “k” being a natural number. The FSEs connected to the k-th connection line have different sizes.
