1. A flexible display module, comprising:
a flexible display panel comprising a first flat portion, a bent portion, and a second flat portion, wherein the bent portion connects the first flat portion and the second flat portion, and the first flat portion and the second flat portion are parallel to each other;
a support member disposed on a side of the first flat portion adjacent to the second flat portion and positioned between the first flat portion and the second flat portion, wherein the support member is defined with a groove on a side of the support member adjacent to the second flat portion, the groove is defined at an end of the support member adjacent to the bent portion, and the support member is a steel sheet; and
an adhesive member disposed in the groove of the support member and disposed between the support member and the second flat portion, wherein a thickness of the adhesive member is greater than a depth of the groove;
wherein an orthographic projection of the adhesive member on the support member is positioned in the groove; and
an area of a first surface of the adhesive member is less than an area of a second surface of the groove, the first surface is a contact surface of the adhesive member and the groove, and the second surface is a surface of the groove facing the first surface;
wherein a third surface of the support member which is opposite to the bent portion is flushed with both a boundary between the bent portion and the first flat portion and a boundary between the bent portion and the second flat portion in a thickness direction of the support member; and
a surface of the adhesive member opposite to the bent portion and the third surface are not flush in the thickness direction of the support member.
 
8. A flexible display module, comprising:
a flexible display panel comprising a first flat portion, a bent portion, and a second flat portion, wherein the bent portion connects the first flat portion and the second flat portion, and the first flat portion and the second flat portion are parallel to each other;
a support member disposed on a side of the first flat portion adjacent to the second flat portion and positioned between the first flat portion and the second flat portion, wherein the support member is defined with a groove on a side of the support member adjacent to the second flat portion, and the groove is defined at an end of the support member adjacent to the bent portion; and
an adhesive member disposed in the groove of the support member and disposed between the support member and the second flat portion;
wherein an orthographic projection of the adhesive member on the support member is positioned in the groove; and
an area of a first surface of the adhesive member is less than an area of a second surface of the groove, the first surface is a contact surface of the adhesive member and the groove, and the second surface is a surface of the groove facing the first surface;
wherein a third surface of the support member which is opposite to the bent portion is flushed with both a boundary between the bent portion and the first flat portion and a boundary between the bent portion and the second flat portion in a thickness direction of the support member; and a surface of the adhesive member opposite to the bent portion and the third surface are not flush in the thickness direction of the support member.
