Patent ID: 8294859

Claim:
A transflective liquid crystal display device, comprising: a first substrate; a second substrate disposed opposingly to the first substrate, in which transmission and reflection regions are formed; and a liquid crystal layer interposed between the two substrates, whose twist angle θ is 0°<θ<30°, wherein a quarter wave plate, a first half wave plate and a first polarizing plate are disposed on a surface of the first substrate from the first substrate side, the surface being opposite to the liquid crystal layer, wherein a liquid crystal film, a second half wave plate and a second polarizing plate are disposed on a surface of the second substrate from the second substrate, the surface being opposite to the liquid crystal layer, wherein a nematic hybrid orientation, in which a polymeric liquid crystal substance is formed in a liquid crystal state, of the liquid crystal film is fixed, wherein an optical axis of the quarter wave plate is disposed to be orthogonal or substantially orthogonal to that of the liquid crystal film, and a bisector of orientation directions on the first and second substrate sides of liquid crystal molecules of the liquid crystal layer is substantially parallel to an orientation direction of liquid crystal molecules of the liquid crystal film, and wherein, when an angle formed by an absorption axis of the first polarizing plate and a lag axis of the first half wave plate is assumed to be α and an angle formed by the lag axis of the first half wave plate and a lag axis of the quarter wave plate is assumed to be β, the first polarizing plate, the first half wave plate and the quarter wave plate are disposed to satisfy the following expressions (9) and (10); 42°≦β−α≦48° (9) 45°<α<90°.
