SWITCH LIQUID CRYSTAL PANEL, MOBILE TELEPHONE WITH OPENING AND CLOSING MECHANISM, AND DEVICE AND METHOD FOR KEYING TEST

摘要

PROBLEM TO BE SOLVED: To prevent hazy unevenness resulting from the repetitive opening/closing operation of a mobile telephone having an opening/closing mechanism in which a switch liquid crystal panel is incorporated. SOLUTION: Spacers 13 which have a≤4% CV (coefficient of variation) value and whose surfaces are made sticky are provided between two substrates constituting a switch liquid crystal panel by 300±100 pieces/mm2scattering density. A hazy unevenness of the mobile telephone having the opening/closing mechanism in which the switch liquid crystal panel is incorporated can effectively be prevented by using the spacers of the above constitution.
