1. A display device, comprising:
a cell matrix including a first cell line and a second cell line, wherein the first cell line includes first cells sharing first row lines, and the second cell line includes second cells sharing second row lines;
a redundancy integrated circuit including a redundancy cell line including redundancy cells, wherein the redundancy cells share a third row line and are connected to the first and second cells through a plurality of column lines and a plurality of connection lines;
a display driver integrated circuit (DDI) configured to replace the first cell line or the second cell line with the redundancy cell line through the first row lines, the second row lines, and the third row line based on whether the first and second cell lines include a bad cell of the cell matrix; and
a memory configured to store bad cell-related information associated with the bad cell and output a replacement selection signal, the replacement selection signal identifying the bad cell of the cell matrix.
