Composition for optical film, and films and display device

An optical film includes a first compensation film and a second compensation film having a retardation for incident light different from the first compensation film, wherein the first compensation film includes a first liquid crystal layer including liquid crystals which are obliquely tilted relative to a surface of the first compensation film, and the second compensation film has a refractive index satisfying Relationship Equation 1 and Relationship Equation 2.&#x2003;&#x2003;Relationship Equation 1&#x2003;&#x2003;Relationship Equation 2

Compensation film and display device including the same

An antireflection film includes a polarizer, a first phase delay layer, and a second phase delay layer, where at least one of the first phase delay layer and the second phase delay layer includes a liquid crystal layer, and the liquid crystal layer includes liquid crystals oriented in a direction tilting obliquely with respect to a surface thereof.

Antireflection film and organic light emitting diode device including the same

An organic light emitting device includes an anti-reflection film including a polarizer and a compensation film positioned on the polarizer and including a liquid crystal layer which includes liquid crystals oriented in a direction tilting obliquely with respect to a surface of the liquid crystal layer extending in a horizontal direction in a cross sectional view, tilt angles of the liquid crystals are gradually larger from the first side to the second side, a maximum tilt angle of the liquid crystals with respect to the surface of the liquid crystal layer is from about 15&#xb0; to about 80&#xb0;, and in-plane retardation (R) of the liquid crystal layer for incident light of a 450 nm wavelength and a 550 nm wavelength satisfies a Relationship 1.

Antireflection film and organic light emitting device provided with the same

An organic light emitting device includes an anti-reflection film including a polarizer and a compensation film positioned on the polarizer and including a liquid crystal layer which includes liquid crystals having oriented direction tilting obliquely with respect to a surface of the liquid crystal layer extending in a horizontal direction in a cross sectional view.
