The invention provides an LED substrate and an LED light bar using the LED substrate. Light-pervious holes are formed in the side face of each crystal fixing position of the LED substrate, when encapsulation is carried out, LED crystals are fixed to the crystal fixing positions, fixing glue is applied on the crystal fixing positions in a point injection mode at the same time, and the light-pervious holes are filled with the fixing glue. Due to the fact that light rays emitted by the LED crystals pass through the fixing glue first and are then emitted into air, part of the light rays can be refracted at the interface of the fixing glue and the air and then directly emitted into the air, part of the light rays are reflected back into the fixing glue, are transmitted to the other side of the substrate through the light-pervious holes and are emitted from the other side of the substrate, restriction of the substrate on the light rays emitted by the LED crystals is reduced greatly, even if the substrate is made of nontransparent materials, the light rays emitted by the LED crystals can be emitted through the substrate, and light emitting by 360 degrees is achieved.
