Abstract: A collection device includes a container that retains a collection liquid and that has a channel through which intake gas travels above the collection liquid retained, and a rotating body that is provided inside the container and that rotates around a rotation axis extending in a direction intersecting an up-down direction. The rotating body has a first blade that protrudes in a direction intersecting the rotation axis. The first blade has a filter that captures a target object included in the intake gas. The filter moves, along with rotation of the rotating body around the rotation axis, from a position inside the channel to a position immersed in the collection liquid. Thereby, the collection device collects, into the liquid, the target object included in the intake gas.

Abstract: A plasma display device has a first plate and a second plate which face each other with a discharge space therebetween, and a sealing member which is provided between the first and second plates to seal the discharge space at edges of the first and second plates. A plurality of electrodes are formed on the inner major surface of the first or second plate. An electrode diffusion preventive layer is formed in each area where the plurality of electrodes cross over the sealing member, so as to avoid direct contact between the plurality of electrodes and the sealing member. As a result, problems such as breaking of the electrodes can be avoided. This construction is especially effective when the electrodes contain Ag.
