Provided is a display apparatus that includes a panel assembly having a front panel and a rear panel coupled to the front panel and a plurality of discharge electrodes to which power is applied; a chassis base assembly that is combined with the panel assembly and on which a driving circuit unit is formed; a plurality of signal transmitting units that electrically connect the discharge electrodes and the driving circuit unit; and a silicon protection member which is formed on at least an end of each of the signal transmitting units to surround connection portions between the signal transmitting units and the discharge electrodes of the driving circuit unit, and comprises a silicon layer that seals the connection portions from the outside and an electromagnetic wave shielding material that is mixed in the silicon layer to block electromagnetic waves generated by the discharge electrodes or the driving circuit unit and has an electromagnetic wave shielding range from 1 to 200 dB. The display apparatus can prevent yellowing, and at the same time, can block electromagnetic waves.
