A packaging structure of a vertical LED chip includes at least a support system, a glue cup that connects to periphery of the support system, a LED chip with light absorption substrate over the support system and packaging glue distributed in periphery of the LED chip, wherein the packaging structure also comprises a baffle that surrounds the outer side wall of the light absorption substrate. Adding of a baffle structure in the support system of the packaging structure can effectively prevent light from being absorbed by the light absorption substrate and reflect such light out of the packaging structure, thus increasing probability of light emitting and improving light intensity of the vertical LED chip.
