A display apparatus includes a display panel and a backlight for the display panel. The backlight has a reflector with a plurality of regularly shaped, reflectively embodied cavities which are arranged in a grid. The reflector also has irregularly shaped, reflectively embodied cavities in at least one peripheral region. In addition, the backlight has a plurality of light sources arranged in the cavities.

The present invention relates to a light emitting device (1) comprising a substrate (2) comprising a plurality of individually controllable light sources (3) adapted for, in operation, emitting light, and at least one insert (4) comprising at least partially light-blocking material and having a longitudinal extension being parallel to the substrate (2). The insert (4) comprises a plurality of transverse elements (5) having a proximal end (5) arranged in proximity of the substrate (2) and a distal end (5) arranged at a distance from the proximal end (5). The transverse elements (5) are substantially perpendicular to the substrate (2), the plurality of transverse elements (5) dividing the substrate into at least a first segment (6) comprising a first group of the light sources (3), a second segment (6) comprising a second group of the light sources (3), and a third segment (6) comprising a third group of light sources (3).
