- the reinforcing material may be embodied in the same curable resin as the sealant, and the reinforcing seal 180 may be formed in a form of applying a curable resin to a portion to form the reinforcing seal 180 and curing the curable resin to be cured.
- the reinforcement seal 180 may be installed to cover the sealing seal 160 together.
- the curable resin implemented as a reinforcement may be a natural curable resin or a thermosetting resin, but may be a UV resin cured by ultraviolet rays to minimize damage to pixels due to heat. It may be a material of high hardness.
- the reinforcing material may be applied by the coating nozzle 230, and the coating nozzle 230 may be a TFT substrate extending from the end of the color filter substrate 150. It may be installed to be inclined at a predetermined angle to spray the reinforcement toward the end of 110.
- the coating nozzle 230 When the coating nozzle 230 is inclined to apply the reinforcing material, the reinforcing material is moved from the end of the color filter substrate 150 toward the end of the TF substrate, and the remaining foreign substances of the pixel exposure part are swept together to end the TF substrate. By being discharged to, it is possible to remove the foreign matter with the installation of the reinforcing seal.
- the reinforcing material when discharged from the TFT substrate 110, by flowing down from the end of the TFT substrate 110, the end of the TFT substrate 110 is covered by the reinforcing seal 180 and cured It is possible to prevent the inflow of foreign substances between the reinforcing seal 180 and the TFT substrate 110 is formed.
- the stretched display panel 100 is driven by supplying power to the stretched display panel 100 as in the preliminary inspection, thereby determining the occurrence of noise.
- the final inspection may be performed by taking a detailed inspection by photographing the display panel 100 by a camera, or may be performed by visual inspection.
- the stretched display panel 100 When the final inspection passes, the stretched display panel 100 according to the embodiment of the present invention is completed, the manufactured stretched display panel 100 is delivered to the state, or stretched display panel 100
- the stretched display panel 100 may be used by installing the device to be installed.
- the manufacturing method of the stretched display panel 100 according to an embodiment of the present invention can also be applied to use as a method for recovering the stretched display panel 100 classified as defective due to the occurrence of noise.
- the stretched display panel 100 manufactured by the method of manufacturing the stretched display panel 100 according to the embodiment of the present invention has a color filter substrate to expose the horizontal pixel line 113 as shown in FIG. 8.
- the TFT substrate 110 protrudes more than 150, and a sealing seal is installed at the end of the color filter substrate 150 to prevent the polymer liquid crystal layer from leaking out.
