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.

A display device includes a display panel including an active region, a peripheral region adjacent to the active region, pixels in the active region, a first crack line in the peripheral region to surround the portion of the active region in plan view, a second crack line in the peripheral region, under the first crack line, and insulated from the first crack line, and a third crack line in the peripheral region, above the first crack line, and insulated from the first crack line and the second crack line.

Display device and method for inspecting display device

A method of testing a display device including a display panel which displays an image and a driver which drives the display panel including measuring a driving operating current in a state where the driver is enabled and the display panel is disabled, and determining whether the driver is defective, based on the driving operating current and measuring a display operating current in a state where the driver and the display panel are enabled, and determining whether the display panel is defective, based on the display operating current.

Method of testing display device

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.
