Abstract
An active matrix substrate includes: pixel electrodes for display which are disposed in a matrix; active elements for controlling input and output of signals to the pixel electrodes; a driving circuit unit for scanning signals for controlling ON and OFF operation of the active elements in a sequential manner; and a driving circuit unit for data signals for inputting and outputting data to the pixel electrodes via the active elements. A clock signal line in at least one of the driving circuit unit for scanning signals and the driving circuit unit for data signals is formed from a thin metal film for scanning signal lines, and a constant voltage line is formed from a thin metal film for data signal lines.
