(54)Liquid crystal display device


(57) A liquid crystal display device includes a substrate (110), a thin film transistor 154c, 154h, 154l) disposed on the substrate, a plurality of color filters (230) disposed on the substrate, a light blocking member (220) disposed between the plurality of color filters and on the thin film transistor, and a pixel electrode disposed on at least one of the plurality of color filters. The pixel electrode comprises a planar shape electrode (192h, 192l) and a plurality of minute branches (193h, 193l) extending from the planar shape electrode. The at least one of the plurality of color filters or the light blocking member comprises a step forming portion (220p) overlapped by the planar shape electrode.
