The present invention is a scintillator panel including: a substrate, a barrier rib formed on the substrate, and a scintillator layer containing a phosphor filling cells divided by the barrier rib, wherein the scintillator layer is formed of a plurality of layers having different phosphor concentrations. The present invention provides a scintillator panel in which formation of the barrier rib makes it possible to improve image clarity and obtain a sufficient amount of emitted light.

Scintillator panel

A manufacturing method for a plasma display member wherein generation of defects such as interruption and short-circuit of a pattern obtained after exposure and development is suppressed and yield is improved, even when a foreign material is adhered on a photo mask or photo mask is scratched. An exposing method for a display member wherein a display member having a photosensitive layer formed on a base substrate is exposed through a photo mask having a desired pattern. The exposing method for the display member is characterized in that the photo mask and the base substrate are relatively shifted during exposure operation.

Display member exposing method and plasma display member manufacturing method

A plasma display member comprises a plurality of substantially stripe-shaped address electrodes () formed on a substrate (), a dielectric layer () covering the address electrodes, main barrier ribs () located on the dielectric layer and formed substantially in parallel with the address electrodes, and auxiliary barrier ribs () formed orthogonal to the main barrier ribs. In the plasma display member, the pitch (Pt) between the outermost main barrier rib of the main barrier ribs located in the non-display region on both sides in the lateral direction of a display region and the main barrier rib adjacent to the outermost main barrier rib is integer times the pitch (Pt) between the main barrier ribs located in the display region, where the integer is two or more. In addition, exposure processing is performed a plurality of times by using a photomask having a specific shape, thereby making it possible to obtain a plasma display having a high display quality and a high productivity.

Liquid crystal display device

Disclosed is a microlens array sheet for a liquid crystal display including a first substance layer and a second substance layer having a refractive index less than that of the first substance layer. A plurality of minute unit lenses are formed by providing concaves and/or convexes to an interface between the first and second substance layers. When a ray having entered into the sheet from the normal-line direction of the second substance layer exits from the surface of the first substance layer, an refractive angle relative to the normal line of the surface of first substance layer is not less than 30 degrees. When this microlens array sheet is attached to the surface of a liquid crystal cell of a liquid crystal display, an improved large angle of visibility can be obtained.
