Description

【Technical field】 [0001] The invention relates to a low temperature polysilicon (Low Temperature Poly-Silicon, LTPS) display device and a manufacturing method thereof. 【Background technique】 [0002] Transistor-driven liquid crystal displays have gradually replaced cathode ray tubes and become the mainstream of displays because of their thin and light advantages. However, with the vigorous development of information technology and the demand for higher resolution and large capacity of information display, the performance of traditional amorphous silicon thin film transistor-driven liquid crystal display (a-si TFT LCD) is no longer sufficient, so the industry began to develop The advantage of the low-temperature polysilicon display device technology with better performance is that the driving circuit can be directly fabricated on the glass substrate (System On Glass, SOG), so as to effectively reduce the cost of the integrated driving circuit and meet the demand of the flat p...
