제1광을 방출하도록 구성된 제1 화소를 포함하는 컬러필터와 이를 포함하는 전자소자에 대한 것이다. 상기 제1 화소는 양자점 복합체를 포함하고, 상기 양자점 복합체는, 매트릭스 및 상기 매트릭스 내에 (예컨대, 임의로(randomly)) 분산되어 있는 복수개의 양자점들을 포함하고, 상기 복수개의 양자점들은, 크기 분석에서, 제1 피크 입자 크기 및 제2 피크 입자 크기를 가지는 다봉분포(multi-modal distribution) (예컨대, 이봉 분포(bimodal distribution)) 를 나타내고, 상기 제2 피크 입자 크기는 상기 제1 피크 입자 크기보다 크고, 상기 제1 피크 입자크기와 상기 제2 피크 입자 크기 간의 차이는 5 nm 이하이다. A color filter including a first pixel (or color conversion region) that is configured to emit a first light and a display device including the color filter. The first pixel includes a (first) quantum dot composite (or a color conversion layer including the quantum dot composite), wherein the quantum dot composite may include a matrix and a plurality of quantum dots dispersed (e.g., randomly) in the matrix, wherein the plurality of the quantum dots exhibit a multi-modal distribution (e.g., a bimodal distribution) including a first peak particle size and a second peak particle size in a size analysis, wherein the second peak particle size is greater than the first peak particle size, and a difference between the first peak particle size and the second peak particle size is less than or equal to about 5 nanometers (nm) (e.g., less than or equal to about 4.5 nm).
