Abstract

The invention discloses a display module and a display device. A display panel comprises a display part, a bending part and a binding part, and the binding part is located on the backlight side of the display part. The supporting stacking structure is arranged on the backlight side of the display part, an inner cavity is defined by the bending part and the supporting stacking structure, a part of the side surface of the supporting stacking structure retracts inwards to the side face of the binding part to form a first gap space, and the first gap space communicates with the edge area of the inner cavity. The first colloid comprises a main body part and an auxiliary part, the inner cavity is filled with the main body part, the first gap space is filled with the auxiliary part, and the Young modulus of the auxiliary part is smaller than or equal to the Young modulus of the main body part. The first gap space is filled with the auxiliary part, so that the material of the main body part is prevented from overflowing from the first gap space, and the comprehensive supporting performance of the main body part on the bent part is improved; and secondly, the damage to the display panel due to the large Young modulus of the auxiliary part in the subsequent pressing process is reduced.
