PURPOSE:To enhance manufacturing efficiency and to improve economy by concurrently performing the processes for decreasing the resistance values of two wirings of a power source line, a signal lines, and the like. CONSTITUTION:A first window part 14 is formed in an insulating layer 12 which is formed on a substrate 11. A second window part 24 is also provided in a resist 41. Then a conducting material 14 is coated over the substrate 11. The conducting material constitutes a conducting layer 21 in the window part 14. Then the conducting material is also embedded in the second window part 42, and it is made to be the wiring 13. Then the resist 41 is removed and the conducting material 43 is removed at the same time. Thereafter, a conducting layer is formed by using a specified mask, and the wiring 13' and wirings 13 and 31 are completed. |
