In addition to pursuing large size, the current process technology of liquid crystal display panels is also moving toward lighter and thinner, especially when liquid crystal displays are used in portable 'electronic products, the thickness of liquid crystal display panels'. The size of the final product is directly affected, so there is a strong demand for the thinning and weight reduction of the liquid crystal display panel. 1 However, the conventional substrate thinning technique still has limitations. Once the substrate is thinned to a certain thickness or less, The substrate is prone to deflection, and it is no longer possible to continue the thinning process, otherwise it will affect The overall flatness of the liquid crystal display panel may cause fragmentation; for example, the conventional substrate thinning technique can only use the fluoric acid (HF) solution to inscribe the glass substrate from 0.5 mm (mm) to 0.3 mm. (mm), can no longer continue to thin, 200923471 Otherwise will adversely affect the flatness of the opposite substrate, the thinning effect of the conventional technology does have its limitations. In view of this, in order to provide a thinner and lighter liquid crystal display, how to enter - The step of reducing the thickness of the substrate of the panel has become an important issue to be solved in the industry. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for thinning a display panel device, the method of the present invention is used twice The single-side thinning process is used to thin the two substrates respectively.

Further, the manufacturing of the present invention The method can provide a better thinning effect and meet the requirements of mass production. To achieve the above object, the present invention provides a method for thinning a display panel device, the display panel device comprising a first substrate and a second The method for the thinned panel device comprises the steps of: first thinning the first substrate; then supporting the thinned first substrate; and thinning the second substrate. In one embodiment, the support is thinned The step of the first substrate is at least partially attached to the outer side of the thinned first substrate; in another embodiment, the step of supporting the thinned first substrate is attached by a carrier plate. The outer side of one of the thinned first substrates; wherein the carrier plate is attached to the outer side of the thinned first substrate by a glue. The above objects, technical features, and advantages of the present invention will become more apparent from the following description. The following examples and drawings are intended to illustrate the invention and are not intended to limit the invention. Referring first to Figures 1A through 1G, Figures 1A through 1G are schematic views of one embodiment of a method for thinning a display panel device of the present invention. In this embodiment, the display panel device includes a first substrate 10 and a second substrate 20, and the first substrate 10 and the second substrate 20 are first assembled to each other. The first substrate 10 may be formed with a thin film transistor array, for example, at least one switching element and at least one halogen electrode, and the second substrate 20 forms, for example, a color filter layer thereon. The first substrate 10 and the second substrate 20 can be bonded by a sealant 30, and an intermediate is interposed between the first substrate 10 and the second substrate 20, for example, a liquid crystal layer 40 is injected. The material of the first substrate 10 and the second substrate 20 is a hard or soft material such as glass or plastic, and the materials of the first substrate 10 and the second substrate 20 may be the same or different, and are not limited herein. At present, the substrate material used in the liquid crystal display panel is mainly glass, mainly because the glass has high temperature resistance, chemical resistance, and high stability. In addition, for the convenience of description, the initial thicknesses of the first substrate 10 and the second substrate 20 in this embodiment are respectively t1, but the initial thicknesses of the first substrate 10 and the second substrate 20 may be the same or different. The thickness of the invention can still be practiced. The method for thinning a display panel device of the present invention mainly comprises the steps of: first thinning the first substrate 10; then supporting the thinned first substrate 10'; and then thinning the second substrate 20 with 200923471. The first substrate 10 and the second substrate 20 may be thinned in the following manner: (1) Chemical etching method: etching a substrate by using a fresh solution such as a hydrofluoric acid (HF) solution; For example, the etching solution is sprayed or sprayed on the substrate to etch the substrate or the substrate is placed in an etching bath having an etching solution for etching, wherein the etching groove may have a jig to set the substrate, and bubbles may be formed in the etching groove. Come back to the substrate. (2) Polish method: The polishing apparatus physically or mechanically grinds the substrate, wherein the polishing apparatus may include a polishing pad or an abrasive. (3) The chemical cutting method is combined with the polishing method. As shown in FIG. 1A to FIG. 1C, after the first substrate 1A and the second substrate 2 are assembled, the edge of the first substrate 1 and the second substrate 20 may be preliminarily utilized by a sealed engine P32. Sealing is performed to prevent other solvents or materials (such as etch solution or abrasive) used in subsequent processes from entering between the first substrate 1 and the second substrate 20; further, as shown in FIG. 1C, selectively formed The protective layer 12 is on the outer side of one of the second substrates 20. The protective layer 12 is, for example, a wax-containing film, a nitride, a thin film of a platinum metal, or other film resistant to a strong acid or anti-abrasive material. Then, the first substrate 10 can be thinned, and the thinning can be performed by the above-described chemical etching, mechanical polishing, or a combination thereof. For example, the first substrate 10 is thinned, for example, by chemical etching. After the first substrate 10 is etched in the strong acid solution for a predetermined period of time, the thickness of the first substrate 10 is originally thinned to t2 to form the thinned first substrate 10' as shown in Fig. 1C. Referring to FIGS. 1D to 1F, after thinning the first substrate 10, a 200923471 carrier 50 can be attached to the outer side of the thinned first substrate 1' to carry the thinned The first substrate 10 avoids deflection due to the thickness of the substrate being too thin. In an embodiment, the carrier 50 can be attached to the outer side of the thinned first substrate 10 by using the adhesive material 52 to support the thinned first Qin plate, so that it can be avoided. The thinned first substrate 10' is flexibly deformed, resulting in destruction and reduced productivity. Next, as shown in FIG. 1E, the second substrate 20 is thinned, and similarly, the thinning can be performed by chemical etching, mechanical polishing, or a combination thereof to form a thinned second substrate. 20'. For example, in the embodiment, if the thinned second substrate 20 is performed by chemical etching, after the second substrate 2 is etched in the strong acid solution for a predetermined time, the thickness of the second substrate 2 is originally Tl thinning to
