Provided is a quantum dot light-emitting device and a display apparatus including the same. The quantum dot light-emitting device comprises: an anode; a cathode; a hole transport layer disposed between the anode and the cathode; a light-emitting layer disposed between the hole transport layer and the cathode, the light-emitting layer including a quantum dot having a core-shell structure; and a buffer layer disposed between the hole transport layer and the light-emitting layer, wherein the buffer layer contains an organic compound or derivatives thereof. The external quantum efficiency and device stability are improved. an aromatic hydrocarbon compound or derivatives thereof having a functional group selected from the group consisting of a hydroxyl group (&#x2014;OH), a carboxyl group (&#x2014;COOH), an amino group (&#x2014;NR, &#x2014;NH, &#x2014;NH, where R is a C1 to C6 monovalent hydrocarbon group or derivatives thereof) and a thiol group (&#x2014;SH).
