Abstract:
A liquid crystal display comprising:a) two electrode substrates, which are arranged opposite to each other;b) a plurality of spacers, which are interposed between the electrode substrates, thereby confronting each of the electrode substrates and maintaining a gap distance between the electrode substrates, wherein each of the spacers comprises a particle which has a mean particle diameter of 0.5 to 25 .mu.m, a coefficient of variation of 10% or less in particle diameter, and a fluidity of 30% or more, wherein the fluidity is measured and defined by sieving a powder of the particle by a method comprising the following steps of:i) placing three different types of JIS-Z8801-standard sieves on top of each other, wherein each of the three sieves comprises a brass frame and bronze mesh and wherein the three sieves have an inner diameter of 75 mm, a depth of 20 mm, and a mesh size of 150 .mu.m (100 mesh), 75 .mu.m (200 mesh), and 45 .mu.m (330 mesh), respectively, and wherein the 150 .mu.m (100 mesh) sieve is on top, the 45 .mu.m (330 mesh) sieve is on bottom, and the 75 .mu.m (200 mesh) sieve is in between the other two sieves;ii) spreading 2.0 g of the powder on the entire surface of the mesh of the top sieve so uniformly that a surface of the powder may get as even as possible;iii) vibrating the three sieves up and down at an amplitude of 1 mm and a frequency of 60 Hz for 120 seconds; andiv) defining the ratio by weight (%) of a portion, which passes through the bottom sieve, of the powder to the initial weight of the powder (2.0 g), namely, the mesh-passing ratio, as the fluidity;c) and wherein the particle further comprises a particle body and a plurality of hydrophobic inorganic fine particles which are attached to the particle body; andd) a liquid crystal, which is packed between the electrode substrates.
