An object of the present invention is to prevent the domain from being generated in the pixel end portions so that the transmittance can increase in an IPS type liquid crystal display device where the size of the pixels is extremely small. In the liquid crystal display device according to the present invention, the electrodes close to the liquid crystal layer have a comb-like structure having a linking portion only at one pixel end, the end portion of the comb-like structure has a structure for preventing the domain from growing, the width of the slits in the comb-like structure is greater than the width of the electrodes, and the alignment of the liquid crystal layer has such a pretilt angle that the liquid crystal rises from the end portion in the comb-like structure towards the root in the interface close to the electrode.
