Abstract
This disclosure provides systems, methods, and apparatus for improving angular distribution of light and total light throughput in a display device. A display device can include first and second substrates and an array of display elements positioned between the first and second substrates. A first light blocking layer can be positioned on the first substrate and can define a first plurality of apertures. A second light blocking layer can be positioned on the second substrate and can define a first second of apertures. A plurality of reflective sidewalls can be positioned adjacent to at least one edge of a respective aperture of the first plurality of apertures. The reflective sidewalls can help to improve angular distribution of light and total light throughput of the display device.
