I assume what you are talking about is D antigen in Rh (Rhesus) blood group system. Rh blood group system is the most important blood group system after ABO blood group system (i.e. type A (AA, AO), type AB, type B (BB, BO), type O (OO) ).
The Rh blood group system consists of 50 defined blood-group antigens and the 5 antigens D, C, c, E, and e are the most important. The commonly-used terms Rh factor, Rh positive and Rh negative refer to the D antigen only. Rh factor (Rh- and Rh + depending on D antigen neg/pos) is important for blood transfusion and prevention of hemolytic disease of the newborn or erythroblastosis fetalis (basically the baby and mom have different blood type - Rh- and Rh+ and cause severe immune response - fatal to the newborn)

Why must D-Positive blood not be transfused into a D-Negative patient?
Transfusing D-positive blood into a D-negative patient can lead to an immune reaction. The D antigen is part of the Rh blood group system, and a D-negative individual can produce antibodies against the D antigen if exposed to D-positive blood, potentially causing a severe transfusion reaction.
