The liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer interposed between the first and second substrates, and a plurality of picture-element regions for providing display. The flow profiles are obliquely aligned at an acute angle relative to an axis of rotation of a screen roller interacting with the doctor-type ink fountain. The semiconductor device further comprises a gate insulating layer disposed between the active region and the first gate electrode. In a third step, three impedances that encompass, when displayed on a Smith chart, a narrower range than a range encompassed by the impedances of the first set of three reference loads are determined, where the narrower range includes the impedances calculated in the second step.
