The display panel has a glass backplate (,) a first surface of which is provided with barrier ribs (,) of glass frit. Electrodes (,) are present between the ribs (3). A front member (,) rests on the barrier ribs (,) and is sealed to the backplate (,). The front member (,) has electrodes (,) which extend transversely to the ribs (,). The glass frit of the ribs (,) mainly consists of ZnO, B,O,and V,O,and has a minor content of SiO,, PbO and/or CuO, and BaO and are mechanically strong. The glass frit combines a relatively small thermal coefficient of expansion and a relatively low sintering temperature, which makes the frit particularly suitable for use with a backplate (,) of borate glass, particularly an alkali-free borosilicate glass.
