Abstract
A display device includes a backlight, a first substrate on a path of light output from the backlight, a second substrate facing the first substrate, a light amount control layer between the first and second substrates, a color filter layer on the second substrate at a pixel area, and a light conversion layer between the light amount control layer and the color filter layer. The light conversion layer outputs white light.
Claims25
A display device, comprising:
- a backlight to output light;
- a first substrate on a path of the light output from the backlight;
- a second substrate facing the first substrate;
- a light amount control layer between the first and second substrates;
- a pixel electrode on the first substrate;
- a color filter layer on the second substrate at a pixel area;
- a light conversion layer between the light amount control layer and the color filter layer;
- a polarizer between the light amount control layer and the light conversion layer;
- and
- a common electrode between the light amount control layer and the polarizer, the common electrode comprising a transparent conductor,
- wherein the light conversion layer and the polarizer are in direct contact,
