Provided is a display device: in which correction can be simply made by using spare lines through melt connection even when central portions of a display panel are joined together by repeated exposure using a portion of a mask; and in which a step for cutting the spare lines is unnecessary even when the central portions are not joined together by repeated exposure. The present invention is provided with: thin-film transistors (not shown) disposed for respective pixels in a matrix form on a display screen 25; a plurality of signal lines S20, S21, S23 which respectively connect a thin-film transistor group on a line in one direction and drive circuits 22, 23, 26 for driving the thin-film transistor group; a plurality of spare lines SPL20-SPL23 which are formed on an outer peripheral section of the display screen 25 such that the spare lines can be connected to the signal lines S20, S21, S23, and which are disposed to be spaced apart from each other on the opposite side of the drive circuits 22, 23, 26 with the display screen 25 interposed therebetween; and metal layers ML4, ML5 that cross and sandwich an insulation layer so as to be respectively connectable with spaced end portions of the spare lines SPL20-SPL23.
