Abstract: Provided is a liquid crystal display panel in which both the prevention of low-temperature bubble defects and the prevention of unevenness in brightness by pressure can be achieved without the need of forming multiple types of spacers differing in the height. In a liquid crystal display panel comprising a plurality of spacers 14 arranged between a pair of transparent substrates 11 and 12 and a liquid crystal 13 encapsulated between the transparent substrates, the spacers 14 are of a uniform height and each spacer 14 is substantially in a trapezoidal shape in which the ratio between the top area and the bottom area is 0.3 or less. The spacers 14 are formed on one of the transparent substrates 11 and 12. The spacers 14 are arranged at appropriate density so that the contact area ratio of the spacers' top surfaces in contact with the opposing substrate per unit area is within a range of 0.8%-1.0%.
