Abstract:
1. A method of producing a liquid crystal display device, comprising: a step of providing at least one liquid crystal panel, the at least one liquid crystal panel having a front substrate, a rear substrate, a mixture interposed between the front substrate and the rear substrate, a plurality of electrodes including a pixel electrode which is provided on the rear substrate, a gate line and a source line provided corresponding to the pixel electrode, and a check terminal electrically connected to the gate line and the source line via a check line, the mixture containing a liquid crystal compound and a photopolymerizable compound; a step of forming from the mixture a liquid crystal layer containing the liquid crystal compound and an alignment sustaining layer resulting through polymerization of the photopolymerizable compound by performing light irradiation while applying a voltage to the mixture via the check terminal and the check line; a step of, after forming the liquid crystal layer and the alignment sustaining layer, applying a voltage across the liquid crystal layer from the check terminal to check the liquid crystal panel; wherein, the step of providing the at least one liquid crystal panel comprises a step of producing a plurality of liquid crystal panels, the step of producing the plurality of liquid crystal panels including: a step of providing a first mother substrate which includes the respective front substrates of the plurality of liquid crystal panels; a step of providing a second mother substrate which includes the respective rear substrates of the plurality of liquid crystal panels, the second mother substrate further including an additional terminal provided in a region other than the respective rear substrates of the plurality of liquid crystal panels and an additional line extending from the check terminal of the rear substrate corresponding to at least one liquid crystal panel among the plurality of liquid crystal panels to the additional terminal; wherein the additional terminal is provided at each of both ends in the row direction of the second mother substrate so as to correspond to rear substrates arranged along the row direction, and the additional line includes common line extending from the additional terminal at one of the both ends to the additional terminal at the other of the both ends; a step of attaching together the first mother substrate and the second mother substrate; and in the step of forming the liquid crystal layer and the alignment sustaining layer, the voltage is applied from the additional terminal.
