Embodiment Construction
[0019] The substrate unit, the component substrate, the display device and the manufacturing method of the display device according to the preferred embodiments of the present invention will be described below with reference to the related drawings, wherein the same components will be described with the same reference symbols.
[0020] Before the process of thinning the display device, the surface of the carrier plate and the thin glass substrate will be subjected to cleaning processes such as water washing or ozone ashing. After the cleaning process is completed, the surface of the carrier plate and the thin glass substrate A hydroxyl group (-OH) will be produced. If the carrier plate is directly attached to the thin glass substrate, the subsequent high-temperature process (>250°C) will cause the hydroxyl groups between the two to react to form a silicon-oxygen bond (-Si-O-Si-), making the carrier plate and the thin glass substrate The thin glass substrate is not easy to sepa...

Abstract
The invention discloses a substrate unit, a component substrate, a display device and a manufacturing method of the display device. The manufacturing method of the display device includes: providing a first carrier plate with a first middle layer; arranging a first glass substrate above the first middle layer to form a first substrate unit; forming a first component layer on the first glass substrate to obtain a first component substrate; providing a second carrier plate with a second middle layer; arranging a second glass substrate above the second middle layer to form a second substrate unit; combining the first component substrate and the second substrate unit; separating the first glass substrate and the first middle layer; separating the second glass substrate and the second middle layer to obtain the display device.
Description
technical field [0001] The invention relates to a substrate unit, a component substrate, a display device and a manufacturing method of the display device. Background technique [0002] With the advancement of technology, flat-panel display devices have been widely used in various fields, especially liquid crystal display devices or organic light-emitting diode display devices. Instead of traditional cathode ray tube display devices, it is applied to many types of electronic products, such as mobile phones, portable multimedia devices, notebook computers, tablet computers and other display devices. [0003] With the demand for larger, thinner and lighter display devices, the display panel has been developed from the conventional glass substrate with a thickness of about 0.5 mm to 0.7 mm to a thin glass substrate with a thickness of 0.3 mm (or less). However, when the thickness of the glass substrate is 0.3 mm or less, the process of forming display elements on the surface o...
