Abstract

The invention provides a manufacturing method of an ultrathin display device. The manufacturing method comprises the following steps: forming a bearing base plate; forming a glass base plate; providing a stripping layer so as to temporarily adhere the bearing base plate with the glass base plate; in the manufacture procedure of low-temperature polysilicon, heating the adhered bearing base plate and glass base plate to a preset temperature; stripping the bearing base plate so as to form the ultrathin display device. Compared with the prior art, the proportion of silicon element, oxygen element and nitrogen element in the stripping layer made of silicon oxynitride is set in a preset range so as to reduce the adhesion energy between the bearing base plate and the glass base plate, and thus the glass base plate and the bearing base plate are prevented from being not separated due to the formation of covalent bonds.

Description

Technical field [0001] The invention relates to an ultra-thin display device, in particular to a manufacturing method for the ultra-thin display device. Background technique [0002] In recent years, the ultra-thin liquid crystal display has been manufactured by thinning the glass after the liquid crystal display cell is completed. For example, 0.5mm or 0.4mm glass is used for hydrofluoric acid (HF) etching to 0.2 mm. However, when the glass is thinned to less than 0.1 mm, it is easy to cause problems such as cracking or surface precipitation. In order to improve the thinning process, the prior art has proposed a solution of using double-layer glass (Glass on Glass, GOG) to produce ultra-thin displays below 0.1 mm, which uses ultra-thin glass (Ultra Thin Glass, UTG) and the carrier glass (Carrier Glass) with a thickness of 0.5mm or 0.7mm are bonded together, and then enter the array substrate (Array substrate) process and the color filter substrate (color filter substrate) proc...
