Light-emitting device and display device

Abstract

Disclosed is a light-emitting device including a first electrode and a second electrode arranged facing each other, at least one of the electrodes being transparent or semi-transparent, and a phosphor layer provided as being sandwiched between the first electrode and the second electrode. In the phosphor layer, conductive nano particles and phosphor particles are dispersed in a matrix including a hole-transporting material. Also disclosed is another light-emitting device including a first electrode and a second electrode arranged facing each other, at least one of the electrodes being transparent or semi-transparent, and a phosphor layer sandwiched between the first electrode and the second electrode. This phosphor layer includes a phosphor particle powder containing phosphor particles, the phosphor particle having at least surface covered with a coating layer, the coating layer including a hole transport material and conductive nano particles dispersed in the hole transport material.
