Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises: a substrate, and a limiting layer located on one side of the substrate. A plurality of light-emitting units are defined by the limiting layer, the limiting layer comprises a plurality of grooves, and light-emitting devices are arranged in the grooves; and at least one light-emitting unit further comprises a light conversion layer, and the light conversion layer is located between the light-emitting device and the side wall of the groove in the direction parallel to the plane where the substrate is located. The light conversion layer is arranged between the light-emitting device and the side wall of the groove so that the light conversion path of the light-emitting device can be prolonged, and a light utilization rate is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Display panels may include liquid crystal displays, LCD panels, electrophoretic display panels, organic light emitting display panels, electroluminescent display panels, field emission display panels, surface conduction electron emitter display panels, plasma display panels, micro LED panels, and the like. [0003] In recent years, research has been conducted on light emitting diode (LED, an element made of inorganic materials, etc.) display panels. Light-emitting diode elements have high light conversion efficiency and thus have very low power consumption, and furthermore, light-emitting diode elements are semi-permanent and environmentally friendly and have a long service life, but the prior art light-emitting diode display panels exist The disadvantage of low light utilization rate.
