Abstract
Provided is a display apparatus including a plurality of pixels each composed of an organic electroluminescent device, in which the dependency of a view angle can be reduced without the sacrifice of the luminance of the display apparatus. The display apparatus of the present invention includes a plurality of pixels each composed of an organic electroluminescent device, in which at least one of the pixels is divided into a plurality of areas different in dependency of a view angle.
Claims11
A display apparatus comprising a plurality of pixels each composed of an organic electroluminescent device, wherein one of the pixels is divided into a first area and a second area wherein in the first area luminance is higher than in the second area at a view angle of 0° and luminance is reduced with an increase in the view angle and wherein in the second area luminance is higher when the view angle is a first angle in the range of greater than −90° and smaller than 0° and when the view angle is a second angle in the range of greater than 0° and smaller than 90° and luminance is reduced as the view angle is deviated from the first angle and the second angle;
- wherein luminescent color from a light emission layer in the first area and luminescent color from a light emission layer in the second area are the same color;
- and
- luminescent color at the view angle of 0°, luminescent color at the first angle and luminescent color at the second angle are the same color.
A display apparatus comprising a plurality of pixels each composed of an organic electroluminescent device, wherein the display apparatus has a first pixel and a second pixel which are divided for one kind of luminescent color, wherein the first pixel has a luminance higher than the second pixel at a view angle of 0° and the luminance is reduced with the increase in the view angle and wherein the second pixel has a luminance higher than the first pixel when the view angle is a first angle in the range of greater than −90° and smaller than 0° and when the view angle is a second angle in the range of greater than 0° and smaller than 90° and luminance is reduced as the view angle is deviated from the first angle and the second angle;
- wherein luminescent color at the view angle of 0°, luminescent color at the first angle and luminescent color at the second angle are the same color.
