A display panel (1) has a first substrate (2) and a second substrate (3). The substrates (2, 3) are provided with electrodes (8, 9) and are separated from each other by a plurality of spacers (4). Holes (5) extend through the spacers (4) and the substrates (2, 3) and thus form through holes (5) extending through the display panel (1) making it permeable to gases and/or liquids. The substrates (2, 3) and the spacer (4) form the wall (6) of the respective through hole (5) and thus a space (7) can be sealed between the two substrates (2, 3) without any risk of leakage. |
