1. A sheet for a display panel, comprising:
a base substrate which is flexible and visible and has a flat shape;
a protective member bonded to a lower surface of the base substrate and configured to prevent scratches from occurring on the base substrate and foreign materials from coming in contact during transfer;
a print layer formed to have a predetermined thickness on an edge of an upper surface of the base substrate in a printing method and configured to perform a bezel function by blocking light transmission;
a filling layer configured to cover both of the print layer and the base substrate and have an outer surface formed to be flat and transparent;
an adhesive member which is transparent, covers the outer surface of the filling layer to have an adhesive function, and is bonded to a transparent member forming an exterior of a display panel; and
a foreign material blocking member configured to prevent foreign materials from coming into contact with the adhesive member on an outer surface thereof,
wherein the filling layer is formed prior to the adhesive member, and adhesive strength between the base substrate and the protective member is greater than adhesive strength between the adhesive member and the foreign material blocking member.
