Abstract:
1. An active matrix display device having a display region consisting of sub-pixels arrayed in a matrix fashion, the sub-pixels having switching elements, comprising: a plurality of data signal lines for sending data signals to the sub-pixels; a plurality of scan signal lines for sending scan signals to the sub-pixels; a plurality of common voltage lines for sending a reference voltage to the sub-pixels; first test transistors, each of which is connected to one of the plurality of scan signal lines for sending first test signals thereto; and a plurality of first input terminals, each of which is connected to one of a plurality of the first test transistors; wherein each gate of the first test transistors and each of the common voltage lines are connected to one of the first input terminals, the first test transistors control inputs of the first test signals to the sub-pixels.
