Abstract
An organic light emitting diode device includes an organic light emitting display panel and a circular polarizing plate disposed on the organic light emitting display panel and including a polarizer and a compensation film, where a retardation of the compensation film in a first direction is determined based on a retardation of the organic light emitting display panel in the first direction.
Claims31
An organic light emitting diode device, comprising:
- an organic light emitting display panel;
- and
- a circular polarizing plate disposed on the organic light emitting display panel and comprising a polarizer and a compensation film,
- wherein a retardation of the compensation film in a first direction is determined based on a retardation of the organic light emitting display panel in the first direction.
A circular polarizing plate for an organic light emitting diode device comprising:
- a polarizer;
- and
- a compensation film,
- wherein a retardation of the compensation film in a first direction satisfies the following relationship inequation:
- |Rc2|−|Rc1|>0,
- wherein
- Rc2 denotes the retardation of the compensation film in the first direction, and
- Rc1 denotes a retardation of the compensation film in the first direction set to allow at least one of reflectance and a reflection color of the circular polarizing plate in a side direction, which is measured while a reflector is disposed under the circular polarizing plate, to be minimum.
A compensation film for a circular polarizing plate, wherein the compensation film has a retardation in a first direction satisfying the following relationship inequation:
- |Rc2|−|Rc1|>0,
- wherein
- Rc2 denotes the retardation of the compensation film in the first direction, and
- Rc1 denotes a retardation of the compensation film in the first direction set to allow at least one of reflectance and a reflection color of the circular polarizing plate in a side direction, which is measured while a reflector is disposed under the circular polarizing plate, to be minimum.
