ABSTRACT:
A reflection type liquid crystal display apparatus includes: a first substrate having a plurality of reflecting electrodes; a second substrate having a light transmitting electrode; and a liquid crystal layer disposed between the first substrate and the second substrate. The first substrate includes an insulating substrate, a switching device provided on the insulating substrate for supplying a display voltage signal to the reflecting electrode, a drawing-out electrode connected to the switching device and extending under the reflecting electrode, and an insulating resin layer having a contact hole on the drawing-out electrode. The reflecting electrode is provided on the insulating resin layer, corresponding to each pixel, so as to cover the contact hole, and is electrically connected to the drawing-out electrode at the bottom of the contact hole. The drawing-out electrode has at least two different metal layers in a region larger than a bottom of the contact hole, the region including the bottom of the contact hole, and a metal layer which is an uppermost layer of the drawing-out electrode is removed at the bottom of the contact hole in the direction of a thickness either partially or until an underlying metal layer is reached.
