Abstract
A pixel structure includes a substrate and a thin-film transistor having a first top surface and disposed above the substrate. The first top surface has a first projection area. A data line has a data line adjoining area connected to the thin-film transistor. A pixel electrode has a second top surface and disposed above the thin-film transistor. The second top surface has a second projection area that is greater than the first projection area. The second projection area has a first part and a second part; the first part corresponding to the first projection area is removed by at least 50%; and the second part corresponding to the data line adjoining area is at most 70% removed. The pixel structure omits an insulation layer under the pixel electrode to lower the cost of production and speed up the manufacturing process.
