Method and apparatus for producing liquid crystal display element

Abstract

Abstract PURPOSE:To allow the continuous transfer of a conductive coating over a long period of time and to improve the mass productivity of LCDs with pin terminals by providing plural lines of grooves on the outer peripheral surfaces of spring pins and squeezing the outer peripheral surfaces at the time of a transfer. CONSTITUTION:The apparatus is so constituted that the conductive coating is transferred onto electrode terminals 8 of the LCDs and tapered surfaces 16b squeeze the outer peripheral surfaces of the spring pins 15 on shrinking of coil spring 17s when the front end faces of the spring pins 15 are pressed to the electrode terminals 8 after the conductive coating is stuck onto the outside surfaces of the respective spring pins 15. The preservation of the stuck conductive coating over a long period of time is possible and the coating compd. can be concentrated to the front end parts of the spring pins 15 in spite of an increase in the viscosity of the conductive coating by a secular change if the grooves 15a are provided on the outer peripheral surfaces of the spring pins 15 in such a manner. The transfer is executed stably over a long period of time in this way and the mass productivity of the LCDs with pin terminals is greatly enhanced.
