Abstract
A liquid crystal display comprises two sheets of plastic film, two transparent electrodes respectively formed on one sides of the sheets and opposed to each other with spacer powder therebetween, and liquid crystal material sealed-in between the electrodes. The spacer powder is coated with a hot melt adhesive, such as vinyl acetate adhesive or polyethylene adhesive, by adding an antiflocculating agent, such as polyethylene wax, and spacer powder, such as aluminum oxide, to suspension of the hot melt adhesive, and then drying the suspension. The resultant powder is fixed to the sheets by the adhesive.
