Abstract
In an embodiment, a transflective LCD comprises pixels each comprising a first polarizing layer; a second polarizing layer; a first substrate layer and a second substrate layer opposite the first substrate layer; the first and second substrate layers are between the first polarizing layer and the second polarizing layer; a liquid crystal material between the first and second substrate layers; an over-coating layer adjacent to the first substrate layer; the over-coating layer comprises at least one opening for a transmissive part; a remainder of the over-coating layer forms in part a reflective part; a patterned in-cell retarder adjacent to the first substrate layer; the patterned in-cell retarder covers at least a portion of the reflective part; a reflective layer between the over-coating layer and the second substrate layer; the reflective layer substantially covers the reflective part; the patterned in-cell retarder is between the reflective layer and the first substrate layer.
