Image pickup device and electronic apparatus with an image plane phase difference detection pixel

An electronic apparatus equipped with an image pickup device comprising an image plane phase difference detection pixel for obtaining a phase difference signal for image plane phase difference AF, the image plane phase difference detection pixel comprising:

• a first photoelectric conversion section that generates an electric charge in response to incident light;
• a second photoelectric conversion section that generates an electric charge in response to light that passes through the first photoelectric conversion section and a lower electrode section;
• an upper electrode section that is one of a number of electrodes disposed facing each other across the first photoelectric conversion section, the upper electrode section being formed on a light incident side of the first photoelectric conversion section;
• and
• the lower electrode section that is another of the electrodes disposed facing each other across the first photoelectric conversion section, the lower electrode section being formed on a side opposite the light incident side of first photoelectric conversion section, wherein the lower electrode section includes a first lower electrode section and a second lower electrode section that are unevenly two-divided at a position that avoids a center of the incident light, and a member that transmits the incident light.
