A light field imaging device comprising:
- an image sensor including a sub-microlens array in which a plurality of sub-microlenses are arranged two-dimensionally;
- a microlens array formed over the image sensor, and having a plurality of microlenses arranged two-dimensionally therein;
- and
- a support structure formed between the image sensor and the microlens array for providing an air gap therebetween,
- the support structure comprising:
- a plurality of first support structures formed over the image sensor to support the microlens array, and having a pillar shape;
- and
- a second support structure coupled to the first support structures to contact a bottom surface of the microlens array, and having a plate shape,
- wherein each of the plurality of first support structures comprises a sealing layer formed over a first support layer to fill inside spaces formed by the first support layer.
