Abstract
An electroluminescent element includes a pair of positive electrode and negative electrode facing each other, and at least one phosphor layers formed between the pair of positive electrode and negative electrode. At least one of the phosphor layers is composed of a phosphor layer and a wide band-gap semiconductor layer. The semiconductor layer or the phosphor layer constituting the phosphor layer may be a partially discontinuous layer.
Claims26
An electroluminescent element comprising:
- a pair of electrodes facing each other;
- and
- at least one phosphor layer formed between the pair of electrodes, wherein the phosphor layer includes a phosphor semiconductor with a wide band-gap.
22-24. (canceled)
A display device comprising:
- an electroluminescent array in which electroluminescent elements are arranged in two dimensions, wherein each electroluminescent element comprises:
- a pair of electrodes facing each other;
- at least one phosphor layer formed between the pair of electrodes, wherein the phosphor layer includes a phosphor semiconductor with wide band-gap;
- and
- a thin film transistor connected with one of the pair of electrodes;
- a plurality of x electrodes, in parallel with each other, extending in a first direction in parallel with a face of the electroluminescent array;
- and
- a plurality of y electrodes extending in parallel with a second direction, orthogonal to the first direction, in parallel with the face of the electroluminescent array, wherein the thin film transistor of the electroluminescent array is connected with the x electrode and the y electrode, respectively.
