A method for driving a PDP is provided in which addressing having little influence from operating environment changes is realized without increasing withstand voltage of circuit components, so that a display is stabilized. The method comprises the step of keeping a scan electrode in high impedance state to a power source line over a part or the entire period of a selection waiting period before the scan electrode is biased to a selection potential level.

A liquid crystal display apparatus equipped with a backlight unit includes an LED, a light guide plate for light emission by guiding light from the LED to a liquid crystal panel, an LED board for driving the LED, a reflection sheet interposed between the light guide plate and the LED board, and a chassis on which the LED, the light guide plate, the reflection sheet and the LED board are mounted. The light guide plate has a half length and a half width of the liquid crystal panel, and the reflection sheet has substantially the same size as the light guide plate. The reflection sheet is extended at portions abutting on sides of the chassis to define flanges.

A plasma display panel includes a pair of substrates forming a discharge space between the substrates, and lateral barrier ribs extending in a row direction and longitudinal barrier ribs extending in a column direction that divide the discharge space into cells. Each lateral barrier rib is divided into two portions in the column direction such that a vent passage is formed in the divided portion. In the plasma display panel, raised portions, which are lower than the lateral barrier ribs and connect the lateral barrier ribs divided into the two portions with each other, are formed in the vent passage.

摘要:
On a front substrate, a dielectric layer for accumulating the wall charge is formed, and inside the dielectric layer, a first electrode and a second electrode intersecting each other are formed with a predetermined pitch. The dielectric layer is not flat but is convex at the intersection of the first electrode and the second electrode, and the thickness in the direction of the discharge space from the second electrode at the intersection is larger than the thickness in the remaining area. Consequently, since the electric field distribution at the intersection is coarser than that at places apart from the intersection when discharge is sustained by causing an electric field distribution in the discharge space through the dielectric layer, discharge occurs not at the intersection but in four positions at places apart from the intersection, so that the luminous efficiency per discharge cell is improved.
