A light emitting structure includes a pixel layer having at least one subpixel, a microlens layer having at least one microlens, the at least one microlens aligned with the at least one subpixel for providing a narrowly-confined on-axis emission profile along an on-axis direction, a first filler material layer and a second filler material layer between the pixel layer and the microlens layer, an interface between the first filler material layer and the second filler material layer configured for reflecting a portion of off-axis emissions from the at least one subpixel by total internal reflection (TIR).
