Abstract
A wafer for fabricating a unit pixel is provided. The wafer includes a transparent substrate, and a light blocking layer disposed on the transparent substrate. The light blocking layer includes a plurality of unit pixel regions and at least one observation region. Each of the unit pixel regions has a mounting region for mounting a light emitting device, and the observation region includes the mounting region for mounting the light emitting device and an auxiliary pattern disposed around the mounting region.
