An all-solid secondary battery includes a cathode layer including a cathode active material layer; an anode layer; and a solid electrolyte layer disposed between the cathode layer and the anode layer, wherein the anode layer includes an anode current collector and a first anode active material layer is disposed on the anode current collector, wherein the first anode active material layer includes an organic electrolyte and an anode active material that is capable of forming an alloy with lithium or a compound with lithium, and wherein the organic electrolyte includes an organic salt including an organic cation and an anion.

All-solid secondary battery and method of preparing the same

A display apparatus including an OLED (organic light-emitting device) substrate having a structure in which at least one blue light-emitting unit and at least one green light-emitting unit are stacked, wherein the OLED substrate generates a mixed light of a blue light and a green light; and a color controller provided on the OLED substrate to adjust color of a light generated from the OLED substrate. The color controller includes a first color control element having a plurality of first quantum dots for green conversion; a second color control element having plurality of second quantum dots for red conversion; a third color control element for presenting a blue color; a first color filter provided on the first color control element; and a second color filter provided on the second color control element.
