Abstract
Method of manufacturing liquid crystal display element includes disposing adhesive on at least one of first and second substrates; disposing spacer particles on at least one substrate; supplying liquid crystal material onto at least one substrate; and fixing the substrates together with adhesive spacer particles and liquid crystal material therebetween. The substrates are fixed together by applying pressure and/or heat to the substrates from an end portion toward the other end portion thereof. An impulse applied to each spacer particle can be between 0.001 gf·sec and 0.1 gf·sec in substrate fixing step. Parameter X relating to heating in fixing step can satisfy 200≦X≦3000, where X=(T−20)/(V·D), T is temperature (°C), V is fixing speed (mm/sec) of substrates, and D is diameter of spacer particles (mm). The spacer particles can occupy an area ratio of 0.003 or more to unit area of the substrate.
