타원 편광판(101)은, 두께가 15㎛ 이상인 편광자(10)의 양면에 투명 보호 필름(11, 12)을 구비하는 편광판(1), 및 편광판의 투명 보호 필름(1) 위에 첩합된 위상차층(3)을 구비한다. 타원 편광판은, 이형의 형상을 갖는다. 편광자(1)의 흡수축 방향과 위상차층(3)의 지상축 방향이 이루는 각은 10∼80°이다. 위상차층(3)은, 파장 450㎚에서의 정면 리타데이션 Re(450), 파장 550㎚에서의 정면 리타데이션 Re(550), 및 파장 650㎚에서의 정면 리타데이션 Re(650)가, Re(450)
Disclosed is an elliptically polarizing plate (101) comprising a polarizing plate (1) and a retardation layer (3). The polarizing plate includes a polarizer (10) having a thickness of 15 µm or more and transparent protective films (11 and 12) disposed on both principal surfaces of the polarizer. The retardation layer is bonded onto one protective film of the polarizing plate. The elliptically polarizing plate is a sized piece having an irregularly shape that is not a rectangle in its plan view. An angle between an absorption axis direction of the polarizer and a slow axis direction of the retardation layer is 10 to 80°. The retardation layer satisfies Re(450) < Re(550) < Re(650), wherein Re(450) represents a front retardation at a wavelength of 450 nm, Re(550) represents a front retardation at a wavelength of 550 nm, and Re(650) represents a front retardation at a wavelength of 650 nm, and the retardation layer includes at least one aligned liquid crystal layer in which liquid crystal molecules are homogeneously-aligned.
