Problems solved by technology

[0007] However, when the scan lines are formed, short circuits may be caused between adjacently formed scan lines due to the mixing of impurities.
Similarly, when forming the data lines, due to the mixing of impurities, short circuits may also be caused between adjacently formed data lines
Further, when forming the power supply lines, due to the mixing of impurities, a short circuit may also be caused between adjacently formed power supply lines
In addition, when multiple wirings are formed on the same wiring layer, there is a possibility that the wirings may be short-circuited due to contamination of impurities.
As a result, the pass rate of the display device will decrease
[0008] In addition, along with the increase in the degree of high definition, it is desired to arrange pixel circuits at a high density. However, in this case, when the scanning lines, data lines, and power lines are manufactured, the distance between adjacent wiring lines The short circuit phenomenon is particularly obvious
