Abstract: An IPS-type liquid crystal display device which can prevent the occurrence of meshes flaw irregularities at the time of forming a sealing material for adhering a TFT substrate and a counter substrate by screen printing is provided. Rubbing which determines the initial alignment direction of liquid crystal molecules and a pretilt angle is applied to the TFT substrate and the counter substrate. In the IPS-type liquid crystal display device, it is necessary to set a pretilt angle to 2.5 degrees or less. The sealing material for adhering the TFT substrate and the counter substrate is formed on the counter substrate by screen printing. By setting an angle made by the squeezing direction in screen printing and the rubbing direction to a value which falls within a range from 165 degrees to 195 degrees, it is possible to prevent the occurrence of meshes flaw irregularities.
