A method of manufacturing a liquid crystal display device 10A according to an embodiment of the present invention includes: forming a pixel electrode 19a for each sub-pixel on the surface of a planarization film 18, forming an insulator 20 over the whole surface, simultaneously forming first to third contact holes 21a to 21c so that a drain electrode D, a connection portion 161 of a common line, and the pixel electrode 19a are exposed from the surface of the insulator 20, forming a film of a transparent conductive material over the whole surface, forming a common electrode 22a including a plurality of slits for each sub-pixel, and connecting the common electrode 22 and the connection portion 161 via the first contact hole 21a and connecting the pixel electrode 19a and the drain electrode D via an interface-structured conductive path 23 formed via the second contact hole 21b, the surface of the insulator 20, and the third contact hole 21c. Accordingly, the invention provides an FFS mode liquid crystal display device and a method of manufacturing the same in which the plurality of contact holes can be formed simultaneously in a single step and the pixel electrode and the common electrode are disposed on the planarization film.
