Embodiment Construction

[0024] Please refer to FIG. 5 , which is a schematic view of the first embodiment of the coating device of the present invention. The coating device 40 includes a nozzle device 48 , a loading platform 44 and two supports 45 . The two supports 45 are respectively arranged on both sides of the carrier platform 44, the nozzle device 48 is arranged above the carrier platform 44, and is supported by the two supports 45, and the carrier platform 44 is opposite to the two supports 45 and the nozzle device. 48 removable.

[0025] The carrying machine table 44 includes a carrying surface 441, which is used to carry the color filter 3. The carrying surface 441 can move horizontally relative to the nozzle device 48, and the nozzle device 48 and the carrying surface 441 during the movement process The spacing between them remains the same.

[0026] Please also refer to FIG. 6 , which is an enlarged schematic diagram of another viewing angle of the nozzle device 48 . The nozzle device 4...

Abstract

The invention relates to a coating device which comprises a loading machine platform and a nozzle device; wherein the loading machine platform is used to load a base which is to be coated; the nozzle device is corresponding to the loading machine platform; the nozzle device comprises three arrays of ejection mouths corresponding to the loading machine platform; the three arrays of the ejection mouths are respectively corresponding to coloration units in different colors of a color light filtering plate which is to be manufactured; the projections of the three arrays of the ejection mouths on the lengthwise of the nozzle device is arrayed in interval and in turn. The coating device in the invention can simplify manufacturing steps and improve efficiency. The invention also provides the manufacturing method of the color light filtering plate of the coating device.

Description

technical field [0001] The present invention relates to a coating device for manufacturing a color filter, and also to a method for manufacturing a color filter using the coating device. Background technique [0002] The liquid crystal display device is a passive display device. In order to achieve the effect of color display, it is necessary to provide it with a color filter (Color Filter, CF), whose function is to convert the passing white light into red (R), green (G ), blue (B) three primary color light beams, and cooperate with thin film transistor (ThinFilm Transistor, TFT) layer and other components such as liquid crystal in between to achieve the effect of displaying different color images. [0003] Please refer to FIG. 1 , which is a schematic diagram of a color filter in the prior art. The color filter 1 comprises: a glass substrate 10, a black matrix 11 positioned on the glass substrate 10, a colored layer 12 positioned between the black matrix 11, a transparent ...
