摘要： PURPOSE:To reduce crosstalk by making widths of individual signal lines and common signal lines of matrix signal wiring narrower than those of other sections of the lines at intersections where the individual signal lines and common signal lines intersect each other. CONSTITUTION:A matrix wiring section has such a structure that individual signal lines 25 and common signal lines 26 are arranged in a matrix-like form through insulating layers 3, semiconductor layers 4, and n layers 5 and ohmic junctions are formed by means of contact sections 29. At intersections 28 where the lines 25 and lines 26 intersect each other, the widths of the lines 25 and 26 are made narrower than those of the other sections of the lines 25 and 26. As a result, influences of the capacity coupling between the lines 25 and 26 can be reduced and crosstalk between the signal lines 25 and 26 can be prevented.
