The invention relates to a liquid crystal display device that is used in display portions of electronics devices and a manufacturing method thereof, and an object is to provide a high quality liquid crystal display device where light is inhibited from leaking and a manufacturing method thereof. The projected structure formed of the first through the fourth columnar spacer receiving patterns, the insulating film and the final protective film is formed on the TFT substrate. The projected structure is buried in the columnar spacer disposed on the opposite substrate. Thereby, even when the liquid crystal display panel is surface pressed, both substrates are hardly displaced.
