An OLED image display apparatus driven by a silicon-based CMOS and a manufacturing method are disclosed, where the apparatus includes four same microdisplay units formed through exposure by using a same mask, where each microdisplay unit includes: a display controller, a row driver, a column driver, and a rectangular display effective area, where one of vertexes of each rectangular display effective area is close to each other to form one rectangular whole display effective area, and there is no electronic component between any two rectangular display effective areas. Through proper layout designing and exposure field splicing, the OLED image display apparatus that is driven by a silicon-based CMOS and that has a larger area is implemented.
