ABSTRACT:
A liquid crystal display element including at least two kinds of spherical particles as a gap holding material in which each hardness is different in liquid crystal injected into a gap between a pair of substrates. Particle diameter accuracy of each particle is not more than 4%, a particle diameter of the particle with high hardness is not more than a particle diameter of the particle with low hardness, a number of the particle with high hardness to the particle with low hardness is 1 to 4, an average particle diameter of the particle with low hardness to the particle with high hardness is 1 to 1.05 and compression modulus of the particle with high hardness to the particle with low hardness is 1.14 to 14.3. As a result, gap uniformity can be improved. Moreover, occurrence of gap irregularity at the time of low temperature and of impact can be prevented.
