Abstract
A liquid crystal display device includes a first substrate; a thin film transistor on the first substrate; a first passivation layer on the thin film transistor; a first electrode on the first passivation layer; a second passivation layer on the first electrode; a second electrode of an oxide semiconductor on the second passivation layer; and an alignment layer on the second electrode. The second electrode includes first portions and second conductive portions alternating with the first portions. A surface of the first portions is flush with the second conductive portions.
