Abstract:
A manufacturing method of liquid crystal cells for a liquid crystal display device, comprising:forming a first plurality of liquid crystal cells that include a color filter and a common electrode on an upper substrate; forming a second plurality of liquid crystal cells that include a plurality of gate lines and a plurality of data lines on a lower substrate; forming a gate contact pad in a marginal space of the lower substrate, the gate pad connected to a first group of the plurality of gate lines of one of a common row and common column of the second plurality of cells; forming a data contact pad in the marginal space of the lower substrate, the data pad connected to a first group of the plurality of data lines of the one of a common row and common column of the second plurality of cells; forming a common voltage contact pad on the lower substrate for applying a common voltage to the common electrodes on the upper substrate; forming an assembled substrate by bonding the lower substrate to the upper substrate; separating the assembled substrate into sub-substrates that include at least the second plurality of liquid crystal cells arranged in the one of a common row and common column; introducing liquid crystal material into the liquid crystal cells of the sub-substrate; and inspecting the liquid crystal cells of the sub-substrate by applying a voltage to the gate contact pad, the data contact pad and the common voltage contact pad.
