Abstract
To provide a display panel, such as a PDP, that can reduce noise caused by a collision sound which occurs when a front panel member and a back panel member vibrate while the display panel is being driven. Projections ( ) are provided on a surface of a first panel member facing a second panel member. The first panel member and the second panel member are connected to each other by a connecting material in areas ( ) where the projections intersect barrier ribs ( ). In this way, noise (noise level) caused by a collision sound which occurs when the front panel member and the back panel member vibrate while the display panel is being driven can be reduced.
