In an optical pickup apparatus which includes at least a laser light source and an object lens and can apply a laser beam to different types of optical discs, an aberration correction liquid crystal device is placed on the optical axis of the laser beam emitted from the laser light source. The aberration correction liquid crystal device includes a first electrode section being placed on the side of the laser light source and having a first electrode pattern for correcting aberration concerning a first optical disc, a second electrode section being placed on the side of the optical disc and having a second electrode pattern for correcting aberration concerning a second optical disc different from the first optical disc in type, and liquid crystal being sandwiched between the first and second electrode sections.
