Matrix-type display device.

摘要

A maxtrix-type display device comprises a display electrode board that has a plurality of pixel electrodes (12) arranged into a matrix, a set of scan lines (2) extending in parallel in a direction and a set of signal lines (1) extending in an orthogonal relation with said scan lines so that these lines are arranged between the adjacent pixel electrodes. A spare line (3a, 3b) intersects at least some of said scan lines (2) and/or said signal lines (1) at each end of said set of lines so as to sandwich an insulating film therebetween, and a lead-out line (30a, 30b) is connected to one end of said spare line. The lead-out lines (30a, 30b) are connected to external connecting lines, which are outside of said display electrode board, so that said lead-out lines can be connected to each other through said connecting lines, whereby line breakdowns can be corrected and the correction of the breakdowns entails little or no increase in load capacity, electrical resistance, and noise with respect to the corrected line.
