Abstract
The present invention discloses a method of manufacturing a display unit of a flat display panel having a wide viewing angle. Conventional process, which requires two mask steps for opening contact holes in isolation layers, is improved and merged into only one mask step, whereby the number of masks is reduced from seven to six in fabricating a pixel unit of a FOP LCD panel and the cost of fabrication is also reduced.
