Abstract:
An active-matrix-type liquid crystal display panel comprising:an active matrix substrate including on an insulating substrate: a plurality of pixel electrodes; pixel switching elements individually connected to the pixel electrodes; and a plurality of scanning lines and a plurality of data lines, provided in a lattice form, for driving the pixel electrodes through the pixel switching elements; an opposing substrate including a common electrode, the opposing substrate being adhered to the active matrix substrate with a liquid crystal layer therebetween; data-line inspection-use switching elements, individually connected to the plurality of data lines, for controlling a supply of inspection-use display signals; a data-line inspection-use control signal line for inputting control signals for switching on/off the data-line inspection-use switching elements, the data-line inspection-use control signal line being a common data-line inspection-use control signal line provided for the data-line inspection-use switching elements; and a plurality of inspection-use display signal lines for supplying the inspection-use display signals to the data lines through the data-line inspection-use switching elements, the plurality of inspection-use display signal lines being provided for the data-line inspection-use switching elements so that different display signals are inputted to adjacent data lines.
