Abstract

The present invention relates to a flexible electro-optical apparatus such as a flexible high-resolution liquid crystal display wherein single-crystal silicon semiconductor is used in manufacturing driver circuits and pixel arrays, and a method for manufacturing the same. The flexible electro-optical apparatus according to the present invention comprises a flexible lower substrate portion including device layers where electronic devices are formed on a flexible single-crystal layer; a flexible upper substrate portion to be bonded to said lower substrate portion; and an electro-optical layer between said lower substrate portion and said upper substrate portion.

Description

technical field [0001] The invention relates to a flexible optoelectronic device of a flexible high-resolution liquid crystal display (flexible high-resolution liquid crystal display) and a manufacturing method thereof, wherein a single crystal silicon semiconductor is used to manufacture a driver circuit and a pixel array. Thinning of single crystal silicon wafers is used to fabricate flexible devices with desired properties. Flexible and high-resolution optoelectronic devices such as liquid crystal displays are fabricated by applying the design rules of common semiconductor fabrication processes and fabricating the active layer of the device from single crystal silicon. Background technique [0002] The maximum resolution of an existing liquid crystal display is 180ppi (pixels per inch) in an amorphous silicon thin film transistor (thin filmtransistor, TFT) device (for example, a 15-inch QXGA notebook computer manufactured by Samsung Electronics Co., Ltd. of Korea) , or 2...
