Manufacturing method and manufacturing apparatus of display device
View Patent ↗The present invention is directed to a display device that overcomes the limitation on tact time, and the defective phenomenon attributed to the generation of bubbles, pasting and visual irregularities at the time of laminating a film to a display panel. A polarizer is positioned in parallel to the vicinity of a main surface of a liquid crystal cell by holding two portions of the polarizer at suction stages. A portion of the polarizer is pushed and brought into contact with the main surface of the liquid crystal cell. From the portion of the polarizer, the polarizer is pushed to the main surface toward one end of the main surface along a first direction thereof. The polarizer is pushed to the main surface of the liquid crystal cell toward another end of the main surface in the first direction so as to laminate the polarizer to the main surface.
1. A manufacturing apparatus of a display device which includes a display panel having a main surface which extends in the first direction and in the second direction which intersects the first direction and in which a cut film is laminated to the main surface of the display panel, the manufacturing apparatus of the display device comprising:
a display panel holding member which holds the display panel by way of a back surface thereof opposite to the main surface thereof and moves the display panel in the first direction;
a pair of film holding members which is arranged to face the display panel holding means in an opposed manner, includes a first holding plate and second holding plate which hold a back surface of a laminating surface of the cut film at at least two positions on a coplanar plane, and allows the first holding plate and the second holding plate to move along the coplanar plane; and
at least one laminating member which is arranged between the first holding plate and the second holding plate of the pair of film holding members, brings a portion of the cut film into contact with the main surface of the display panel, and is movable in a reciprocating manner along the main surface of the display panel in synchronism with the movement of the first holding plate and the second holding plate.
2. A manufacturing apparatus of a display device according to claim 1 , wherein after the portion of the film is brought into contact with the main surface of the display panel, the laminating member is moved along the main surface of the display panel in the first direction toward one end of the main surface of the display panel and, thereafter, the laminating member is moved along the main surface of the display panel in the first direction toward another end of the main surface of the display panel whereby the film is laminated to the main surface of the display panel.
3. A manufacturing apparatus of a display device according to claim 1 , wherein the laminating member is a rotatable cylindrical roller.
4. A manufacturing apparatus of a display device according to claim 1 , wherein the laminating member is a curved surface portion or a shape of a portion of the curved surface portion of a tiltable cylinder.
5. A manufacturing apparatus of a display device according to claim 1 , wherein an angle of a motion that the laminating member brings the film into pressure contact with the main surface of the display panel is approximately 45 degrees or less with respect to the main surface of the display panel.
6. A manufacturing apparatus of a display device according to claim 2 , wherein an angle of a motion that the laminating member brings the film into pressure contact with the main surface of the display panel is approximately 45 degrees or less with respect to the main surface of the display panel.
7. A manufacturing apparatus of a display device according to claim 3 , wherein an angle of a motion that the laminating member brings the film into pressure contact with the main surface of the display panel is approximately 45 degrees or less with respect to the main surface of the display panel.
8. A manufacturing apparatus of a display device according to claim 3 , wherein an angle of a motion that the laminating member brings the film into pressure contact with the main surface of the display panel is approximately 45 degrees or less with respect to the main surface of the display panel.
