Abstract
There is provided a liquid crystal display device having color filters on a side of a TFT substrate, in which an orientation film is formed by inkjet printing. The formation of an orientation film by inkjet printing is more advantageous than the conventional flexographic printing in terms of the production cost. It is necessary, however, to reduce the viscosity of the orientation film to be applied by inkjet printing. For this reason, first and second orientation film stoppers are formed between a display area and a sealing portion in a TFT substrate, to prevent the orientation film from flowing to an end of the TFT substrate. The orientation film stoppers are formed by the overlapping of color filters. A profile of the orientation film is defined by the first orientation film stopper. The second orientation film stopper is formed to ensure that the orientation film does not flow to the outside.
