There is provided a liquid crystal display device in which film thickness irregularities and rubbing irregularities of orientation films are minimized in which superior image quality is provided even when columnar spacers are disposed therein. The liquid crystal display device has a structure in which a liquid crystal substance is sandwiched between a pair of substrates facing each other with the space therebetween controlled to a specific value by a plurality of the columnar spacers independent from each other, wherein the placement density of the columnar spacers is 100 to 2000/mm2, and the sectional area of the columnar spacers is 1 to 100 mum2.
