More Information
Summary:According to the present invention, a color conversion substrate comprises: a color conversion unit comprising wavelength conversion particles that excite incident light to emit light of a color different from that of the incident light; a color filter pattern for filtering light emitted from the color conversion unit; and a light reflection layer disposed between the color conversion unit and the color filter pattern to selectively reflect light having a wavelength corresponding to the incident light. Therefore, the color conversion substrate increases optical efficiency. 개시된 색 변환 기판은, 입사광을 여기하여 입사광과 다른 색상의 광을 방출하는 파장 변환 입자를 포함하는 색 변환부, 상기 색 변환부로부터 방출된 광을 필터링하는 컬러 필터 패턴 및 상기 색 변환부와 상기 컬러 필터 패턴 사이에 배치되어 상기 입사광에 대응하는 파장을 갖는 광을 선택적으로 반사하는 광 반사층을 포함한다.
