Next, based on Fig. 7, the action of first embodiment is described.Fig. 7 is used to illustrate the figure of display panel with the action of the sealing material curing device of glass substrate.Fig. 7 (a) is the figure of the stationary state before the running of expression irradiation unit body, and the central shaft and the display panel of irradiation unit body keep approximate vertical with glass substrate.Under this state, at first,,, make the sealing material curing that exposes from the black matrix of periphery to display panel glass substrate irradiation ultraviolet radiation from irradiation unit body 20, and temporary fixed.
Next, shown in Fig. 7 (b) and Fig. 7 (c), the irradiation unit body rotates by mobile unit, and the central shaft of irradiation unit body with stop such as reaching on 30 ° the position with the formed angle θ of the straight line of glass substrate perpendicular to display panel.As under the state that the irradiation unit body is tilted, to display panel glass substrate irradiation ultraviolet radiation.In addition, shown in Fig. 7 (d), under the state that the irradiation unit body is tilted, it is moved in horizontal (X-direction) with glass substrate along display panel, irradiation ultraviolet radiation stops until the position that moves to Fig. 7 (e) simultaneously.Thus, to the encapsulant irradiation ultraviolet radiation of each molding box shape of the part that becomes a plurality of display panels, these a plurality of display panels are made into figure at display panel on glass substrate and dispose.Ultraviolet ray irradiation by the past road shown in Fig. 7 (a)～(e), mainly be positioned at encapsulant in the both sides parallel in the encapsulant to the encapsulant on limit parallel in the encapsulant of each molding box shape and each molding box shape, shine enough ultraviolet rays near the moving direction of irradiation unit body with Y-axis with X-axis.Yet,, owing to there is black matrix, be positioned at the enough ultraviolet rays of encapsulant irradiation in can not the both sides parallel near the moving direction of irradiation unit body with Y-axis to the encapsulant of each molding box shape only by ultraviolet ray irradiation toward the road.
When the irradiation unit body moves to the position shown in Fig. 7 (e) and finish the ultraviolet ray irradiation on past road, at this time-out, and make the irradiating angle of irradiation unit body such shown in Fig. 7 (f), Fig. 7 (g), with reverse toward the road, even it rotates (30 ° * 2) with symmetrical manner, and the irradiation unit body is tilted to the direction opposite with past road.Under this state, display panel is carried out the ultraviolet ray irradiation on multiple road with glass substrate.Shown in Fig. 7 (h), under the state that the irradiation unit body is tilted, it is moved to transverse direction (X-direction) with glass substrate along display panel, simultaneously to the encapsulant irradiation ultraviolet radiation of display panel with the molding box shape of glass substrate.When the irradiation unit body moves to the position shown in Fig. 7 (i) and finish the ultraviolet ray irradiation on multiple road, the irradiation unit body rotates, shown in Fig. 7 (j), the central shaft that returns to the irradiation unit body from heeling condition and display panel be with on the almost vertical position of glass substrate, and turn back to initial position.Like this, constipation Shu Yici back and forth shines.By the ultraviolet ray irradiation on multiple road, can shine enough ultraviolet rays in the road, failing the enough ultraviolet aforementioned encapsulant of irradiation.
Repeat this perseveration, till sealing material curing.In addition, also can preestablish the number of occurrence according to employed lamp and encapsulant.In addition, when carrying out for the second time later perseveration, omit temporary fixed action.
In addition, be used to set the rotation at angle of inclination and the moving of irradiation unit body of irradiation unit body and display panel usefulness glass substrate, also can constitute as follows: promptly do not make the irradiation unit body tilt, move, but display panel is tilted with glass substrate or move, simultaneously from irradiation unit body irradiation ultraviolet radiation.
In addition, when mobile irradiation unit body and irradiation ultraviolet radiation, display panel is less with the exposure of the periphery of glass substrate, for fully carrying out, adopt the high-purity aluminium sheet and the auxiliary mirror of side is set abreast with the moving direction of irradiation unit body to the ultraviolet ray of the periphery parallel irradiation with moving direction.Utilize this a pair of auxiliary mirror, the both ends of the surface of the substrate that can not shine (end face of the forward side among Fig. 7 with inboard end face) to direct sunshine from the irradiation unit body, uv reflectance also shines from tilted direction.
As mentioned above, can from the tilted direction irradiation ultraviolet radiation, and the encapsulant under the black matrix efficiently be hardened to the inside of the periphery end face of a plurality of display panels parts of being made into figure at display panel on glass substrate.
