Description of the Invention: [Technical Field] [0001] The present invention relates to a display device and a manufacturer thereof, and a color filter substrate and a method of fabricating the same. In particular, [0002] [0004] [Prior Art 3 color light-emitting substrate is used to make the display vibrate to display a color image. The color filter substrate includes color (four) elements disposed at different positions of the substrate such as a red filter, an optical element, a green filter element, and a blue calender element. The process of the relay element generally includes a yellow light process. The temperature of the Huangxian process is as high as 200 degrees or more. The color light-emitting substrate of the flexible display device generally uses a flexible material as a substrate, for example, a plastic such as poly(p-diethyl) (pET). However, the surface transition temperature (Tg) of a plastic knee substrate is generally much lower than the temperature of the yellow light process (e.g., the glass transition temperature of the polyethylene terephthalate is about 80 degrees). Therefore, the 'plastic substrate is not suitable for the yellow light process 〇 'S :: - the type of silky color substrate is purely cut on a high-temperature glass substrate to perform a process such as yellow light to form a color filter element. Then, the color filter element on the glass substrate is transferred onto the plastic substrate. However, the process of this method is complicated, which makes the chance of product damage and the yield decrease. In addition, since the material matching of the substrate is limited, the cost is high. Furthermore, since the color filter substrate formed by the transfer method has a film other than the plastic substrate such as glass, the display device of the color filter substrate using the multilayer film has a light transmittance which is reduced and becomes inflexible. .于#99146325 Form No. A0101 Page 3/18 Pages 0992079666-0 201227002 [0005] [0006] [0007] [0009] [0009] 099146325 [Invention] In view of this, a simple color filter substrate is provided.

In one embodiment, the recess 14 is formed by melting the substrate 12 by a laser 20. Since the formation of the recess 14 does not involve a high temperature environment, the method of this example is applicable to the substrate 12 of various materials such as polyethylene terephthalate (PET) having flexibility. In addition, the position, area and depth of the recess 14 can be precisely controlled by adjusting the spot size and energy of the laser 20, thereby greatly increasing the yield of the product.
