BONDING DEVICE OF DISPLAY PANEL, PARTICULARLY REGARDING TO FLEXIBLY COPING WITH CHANGE IN POSITION OF SEALANT, AND REDUCING BONDING PROCESS TIME BY SIMULTANEOUSLY APPLYING LIGHT TO WIDE RANGE OF SEALANT

摘要

PURPOSE: A bonding device of a display panel is provided to appropriately apply ultraviolet rays to a sealant even if a position of the sealant changes, reduce bonding time by simultaneously applying light to two sealants, and sufficiently harden the sealant. CONSTITUTION: A plurality of light applying units(1-1,1-2) are installed, each having a rod-shaped lamp(1a). A light applying unit moving equipment(4) moves the light applying units in first axial direction. A control unit controls movement of the plurality of light applying units. A work stage(5) is installed to load a display panel(20), wherein the work stage is rotative at 90 deg. in a plane. The control unit moves the plurality of light applying units based on pitches of liquid crystal pictures formed on the display panel, and performs light irradiation to only a part on which a sealant(22) is applied. The control unit rotates the work stage to perform light irradiation to a part of the sealant applied in direction orthogonal to the sealant.
