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.
