The process of the display panel of the display devices 10 and 10A to 10C is as follows. First, a mother substrate (not shown) of the substrate 110 and a mother substrate (not shown) of the substrate 120 are provided, wherein a plurality of pixels PX are disposed on an active region of the mother substrate of the substrate 110, and the mother substrate of the substrate 120 does not have the second light-shielding pattern 160. Then, the frame glue 140 is coated on the mother substrate of the substrate 110 or the mother substrate of the substrate 120, and the non-self-luminous display medium 130 is formed in the space surrounded by the frame glue 140. Then, the mother substrate of the substrate 110 and the mother substrate of the substrate 120 are assembled, wherein a portion of the sealant 140 is located on the active region of the mother substrate of the substrate 110. Then, a curing light beam (for example, but not limited to, UV) is irradiated onto the sealant 140 to cure it. Then, the mother substrate of the substrate 110 and the mother substrate of the substrate 120 are diced along the scribe lines according to any desired dimension to form a quasi-display panel including the substrate 110 and the substrate 120, wherein at least a portion of the scribe lines are located on the active region of the mother substrate of the substrate 110. Then, the cut quasi display panel is washed with water to remove particles (particles). Then, forming a second light-shielding pattern 160 on the outer surface 110b of the substrate 110 or the outer surface 120b of the substrate 120; then, a plurality of polarizers 190 are attached to the outer surfaces 110b, 120b of the substrates 110, 120; in this manner, the display panels of the display devices 10 and 10A to 10C are formed.
Note that before the sealant 140 is cured, the second light-shielding pattern 160 is not formed yet. Therefore, the curing light beam can be transmitted from the outer surface 120b of the substrate 120 to the inner surface 120a of the substrate 120 to irradiate the sealant 140; in the process of irradiating the sealant 140 with the curing light beam, the curing light beam is not blocked by the second light-shielding pattern 160 and is not blocked by a light-shielding layer (e.g., a metal layer used for forming data lines, scan lines and/or portions of the active devices T) of the pixel array substrate. Therefore, the sealant 140 can receive sufficient curing light beams, and the curing rate is high, thereby improving the reliability of the display devices 10, 10A to 10C.
In addition, in the process of the display panels of the display devices 10 and 10A to 10C, the curing light beams irradiate the first portion 141 and the second portion 142 of the sealant 140 from the same side, and a cell (cell) formed by inverting the mother board of the substrate 110 and the mother board of the substrate 120 for curing the sealant 140 is not required, so that the display panels of the display devices 10 and 10A to 10C are excellent in mass productivity.
In addition, in the process of the display panels of the display devices 10 and 10A to 10C, the mother substrate of the substrate 110 and the mother substrate of the substrate 120 are cut after the non-self-luminous display medium 130 is sealed by the sealant 140, so as to form the quasi-display panel including the substrate 110 and the substrate 120. Therefore, the display panel can be washed with water before the polarizer 190 is attached, so that particles are not easily left in the finally formed display panel.
Furthermore, since the water washing process can be performed to remove the particles, the polarizer 190 may be attached after the mother substrate of the substrate 110 and the mother substrate of the substrate 120 are cut. Since the polarizer 190 is attached after the cutting process, the polarizer 190 may be selectively retracted or protruded out of the substrate 110, 120, which is helpful for realizing the general display devices 10, 10A, 10B with the retracted polarizer 190 or the full flat high-level display device 10C with the protruded polarizer 190 according to the product requirement.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
