<p>PURPOSE:To permit elimination of a short-circuit generated in a crossing part of two bus lines by providing the slit-shaped aperture of one bus line in such a manner that both ends thereof project to both transverse sides of the other bus line. CONSTITUTION:The slit-shaped aperture 4 along the direction of the gate bus line 2 is provided to the crossing part 3 of said line with the drain bus line 1 at the time of forming the bus lines 2 on a transparent insulating substrate. The aperture 4 is formed to the shape that both ends thereof project to the transverse sides of the line 1. A very small area 7 enclosed by two pieces of laser trimming parts 6 and the aperture 4 can be electrically separated from the line 2 by cutting the line 2 from both ends of the aperture 4 toward either of the transverse sides of the line 2 by a laser trimmer, etc. Selection of the cutting line in such a manner that a short-circuit part 5 enters the area 7 is, therefore, satisfactory if the short-circuit defect exists in the crossing part 3. The area 7 is thereby connected only to the line 1 and is isolated from the line 2. The short-circuiting between the two bus lines is thus eliminated.</p> |
