ABSTRACT:
In the adhesive spacers which are synthesized as by the impact method in a high-speed air current, resin particles formed solely of an adhesive layer are included in a large amount besides those of adhesive spacers. An adhesive particulate composition is obtained by adjusting these resin particles in terms of grain size. The adhesive particulate composition containing (a) adhesive particles having a thermoplastic resin-containing layer cover at least part of the surfaces of the core particles having an average particle diameter in the range of 1 to 20 .mu.m and a coefficient of variation of not more than 10% and (b) adhesive layer particles formed of the thermoplastic resin and having a ratio of the number of (b) the adhesive layer particles to that of (a) the adhesive particles of not more than 30%, adhesive spacers for a liquid crystal display panel formed of the composition, and the liquid crystal display panel using the spacers are disclosed.
