Abstract:
1. An array substrate comprising: a substrate; a pixel part having a plurality of gate lines, a plurality of data lines, and a plurality of pixels electrically connected to the gate lines and data lines, the pixel part formed on the substrate; a driving circuit electrically connected to a first end of the gate lines and which drives the pixel part, the driving circuit formed on the substrate; and a first inspection circuit electrically connected to a second end of the gate lines and which inspects the pixel part in response to an inspection signal, the first inspection circuit formed on the substrate, wherein the first inspection circuit comprises: a plurality of first switching devices connected to the second end of the gate lines; a plurality of second switching devices connected to the first switching devices; a first inspection line coupled to odd-numbered first and second switching devices connected to odd-numbered gate lines; and a second inspection line coupled to even-numbered first and second switching devices connected to even-numbered gate lines, wherein each of the odd-numbered first switching devices comprises a first electrode connected to the second end of the odd-numbered gate lines, a second electrode connected to the first inspection line, and a third electrode connected to the first inspection line, and each of the even-numbered first switching devices comprises a first electrode connected to the second end of the even-numbered gate lines, a second electrode connected to the second inspection line, and a third electrode connected to the second inspection line.
