Abstract

PURPOSE: To manufacture a ring-shaped or channel-shaped display cell with an opening or notch easily at a high yield by injecting liquid crystal and then by carrying out horning work after sealing.
CONSTITUTION: Liquid crystal cell 10 injected with liquid crystal and then sealed is fixed under vacuum 11 on setting table 9. On cell 10, mask material 12 made of rubber, metal or the like is placed and from nozzle 13 set up over it, mixture 14 of abrasive grains and water is sprayed together with high-pressure air to remove unrequired part 8. Thus, opening part 16 which is the unrequired part of ring- shaped liquid crystal cell 15 having liquid crystal layer 20 between substrates 17 and 18, for example, is removed. This method is suitable for the manufacture of a display cell applied to an electronic desk-top calculator, digital watch, etc.
