Abstract

Manufacturing method of a liquid crystal display device having a TFT substrate with a display area in which pixels are arranged, a counter substrate, a sealing material formed in a periphery to bond the TFT and counter substrates, and a liquid crystal layer interposed between an orientation film on the TFT substrate and an orientation film on the counter substrate. The method includes the steps of forming a first color filter, a second color filter, or a third color filter corresponding to each of the pixels in the display area of the TFT substrate, and forming an orientation film stopper by overlapping a portion of the first color filter, the second color filter, or the third color filter, in an area between the display area and the sealing material. A profile of the orientation film formed in the TFT substrate is defined by the orientation film stopper.
