Abstract
Provided is an organic light emitting display device. The organic light emitting display device comprises a display panel; and an optical laminate disposed on the display panel and including a multi-functional layer. The multi-functional layer contains a liquid crystal mixture including a liquid crystal compound and two or more types of dichroic dyes, below the multi-functional layer, the liquid crystal compound is contained, but the two or more types of dichroic dyes are not included and above the multi-functional layer, the two or more types of dichroic layers are contained.
Claims16
An organic light emitting display device, comprising:
- a display panel;
- an optical laminate disposed on the display panel;
- and
- a multi-functional layer within the optical laminate,
- wherein:
- the multi-functional layer contains a liquid crystal mixture including a liquid crystal compound and two or more types of dichroic dyes;
- in a lower region of the multi-functional layer, the liquid crystal compound is present but the two or more types of dichroic dyes are not present;
- in an upper region of the multi-functional layer, the two or more types of dichroic dyes are present;
- the liquid crystal mixture is cured as a linear polarizer in the upper region of the multi-functional layer and is cured as a phase retarder in the lower region of the multi-functional layer;
- the linear polarizer located on the upper region of the multi-functional layer and a phase retarder located on the lower region of the multi-functional layer are arranged continuously by phase separation of the liquid crystal mixture;
- and
- an adhesive is not disposed between the linear polarizer and the phase retarder.
