Abstract
A TFT substrate includes a pixel region which is a rectangular region where a plurality of pixels are formed in a matrix, a frame region which is outside the pixel region and frames the pixel region, a light blocking metal wire which is formed so as to surround the outside of at least three sides of the rectangular pixel region and has slits, a disconnection detection metal wire for detecting disconnection thereof formed outside the light blocking metal wire, two terminals are connected to the disconnection detection metal wire, and common electrodes which are connected to the light blocking metal wire and are maintained at the same potential as a common potential in the pixel circuit.
