  • Patent number: 10403802
    Abstract: It is an object of the present invention to provide an LED panel and an LED display that enhance orientation properties of LEDs and the efficiency of light use with a simple configuration. It is a different object of the present invention to provide a method for manufacturing the LED display panel, the method reducing an increase in process step. An LED display panel according to an aspect of the present invention includes the following: a plurality of chip-on-board LEDs mounted on a substrate, the LEDs each having a light-emitting surface on a surface opposite a substrate side; and a plurality of light-transmissive members. Each light-transmissive member is disposed on the substrate to cover the light-emitting surface of at least one of the LEDs. Each light-transmissive member is configured to enhance the directionality of outgoing light emitted from the LEDs.
