Problems solved by technology
[0021] However, in a structure having a stage on which the lower substrate is placed as in the example disclosed in Patent Document 4, it is difficult to always maintain the perfect level of the stage, and it is also difficult to always monitor its levelness.
However, when the mounting table has an inclination angle, when the upper substrate is pressed to the lower substrate by the mechanical unit, the pressing force is not uniform, and due to the influence of the inclination angle, there are parts where the cell gap is wide and narrow.

The invention relates a sealing method and an apparatus thereof. During the boning operation of a pair of substrates, the upper substrate is fixed on a constant position for accurate positioning and alignment, and a unit gap between the upper substrate and the lower substrate is made to be constant when a carrying stand equipped with the lower substrate is inclined with an angle, so that a unit structure body is obtained, and the quality and the production efficiency are improved. The unit structure body is obtained through the following bonding procedures of the upper substrate and the lower substrate: placing the lower substrate on the carrying stand inside the sealing apparatus; the upper substrate is placed on the lower substrate inside the sealing apparatus; a transparent electrode, formed on an ultraviolet ray passing sheet that is arranged above the upper substrate, is powered on, so that static electricity is generated to clamp the substrates; and ultraviolet ray irridiates under a condition that the upper substrate is pressed downward toward the lower substrate through the ultraviolet ray passing sheet so that pre-coated sealing material is hardened.
Description
technical field [0001] The invention relates to a sealing method and its device. The upper substrate and the lower substrate are carried into the sealing device, the upper and lower substrates carried in are aligned with each other, and the upper and lower substrates are pre-coated on the upper substrate or the lower substrate by ultraviolet (UV) irradiation. By hardening the sealing material on the substrate, the upper and lower substrates are bonded together with the display function layer interposed therebetween. Background technique [0002] Liquid crystal panels, organic EL panels, and electronic paper panels, etc., which are representative examples of panel displays, use a unit structure in which a display function layer capable of displaying an image is interposed between a pair of upper and lower substrates and sealed. In the unit structure in the liquid crystal panel, an alignment film, a transparent electrode, a polarizing filter, etc. are disposed so as to sandwic...
