Abstract: A display device includes a display layer including an active area in which a plurality of pixels is arranged and a peripheral area located adjacent to the active area. The display layer includes a transistor disposed in the active area and including a gate, a source, and a drain, a first crack line disposed in the peripheral area and surrounding a portion of the active area in a plan view, and a second crack line disposed in the peripheral area under the first crack line. The first crack line is insulated from the second crack line.

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 F SEs, 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.
