A light emitting device includes a first light emitting diode configured to emit light at a first peak wavelength, a second light emitting diode configured to emit light at a second peak wavelength that is different from the first peak wavelength, and a third light emitting diode including, from bottom to top, a lower electrode, an organic light emitting material portion, and an upper electrode, where the third light emitting diode is configured to emit light at a third peak wavelength that is different from the first and second peak wavelengths. A pattern definition layer which includes an opaque material covers at least a portion of the organic light emitting material portion and includes an opening overlying the organic light emitting material portion.

A light emitting device includes a backplane, an array of light emitting diodes attached to a front side of the backplane, a transparent conductive layer contacting front side surfaces of the light emitting diodes, an optical bonding layer located over a front side surface of the transparent conductive layer, a transparent cover plate located over a front side surface of the optical bonding layer, and a black matrix layer including an array of openings therethrough, and located between the optical bonding layer and the transparent cover plate.

Lenses and methods for directing light toward a side of light fixture, and methods for manufacturing the same, are disclosed. Embodiments include lenses with an optical axis and a first (e.g., upper) portion that is rotationally symmetric about the optical axis and a second (e.g., lower) portion that is rotationally asymmetric. The first/upper portion can include a cavity that receives an LED and directs light toward the second/lower portion. The asymmetric side can include a convex surface where the light exits the lens, the convex surface extending across the optical axis. Additional embodiments include a planar surface adjacent the convex surface, where the height of the lens decreases along the portion of the convex surface near the planar surface and along the planar surface as the distance from the optical axis increases. In further embodiments, the maximum height of the lens occurs between two horizontal sides of the lens.
