Image sensor including dichroic lens array and electronic device including same

An image sensor including a dichroic lens array is provided. The image sensor includes: a sensor substrate including a first pixel configured to sense light of a first wavelength and a second pixel configured to sense light of a second wavelength; a transparent spacer layer on the sensor substrate; and a dichroic lens array on the spacer layer, in which the dichroic lens array converges light of the first wavelength toward the first pixel, and includes a first lens layer on the spacer layer, a second lens layer on the first lens layer, and an etch prevention layer between the first lens layer and the second lens layer. 提供了一种包括分色透镜阵列的图像传感器。所述图像传感器包括：传感器基板，包括被配置为感测第一波长的光的第一像素和被配置为感测第二波长的光的第二像素；所述传感器基板上的透明间隔层；以及所述间隔层上的分色透镜阵列，其中，所述分色透镜阵列使所述第一波长的光朝着所述第一像素会聚，并且包括所述间隔层上的第一透镜层、所述第一透镜层上的第二透镜层、以及所述第一透镜层与所述第二透镜层之间的蚀刻防止层。
