摘要:
An image display apparatus includes first and second substrates, an electron emitting device, light emitting members, and a spacer located between the first and second substrates. Straight-line ribs higher than the light emitting members are formed on the second substrate with one of the lines of light emitting members interposed between each adjacent pair of ribs. The spacer extends in a second direction intersecting a first direction in which the ribs extend, and is located between the light emitting members adjacent to each other in the first direction. The ribs include first and second ribs, and each first rib includes a wide portion where it intersects the spacer, the wide portion having a large width in the second direction and being higher than parts of the second ribs intersecting the spacer, at least one of the second ribs being disposed between each adjacent pair of first ribs.

An organic electroluminescent device includes, on a substrate, a pixel having a luminescent functional layer which is sandwiched by a first electrode and a second electrode, and a unit pixel group composed of a plurality of the pixels. A scattering portion which scatters luminescent light of the luminescent functional layer is provided in a pixel selected from the unit pixel group.

An electron emission display including an electron emission substrate having at least one electron emission device formed thereon and an image forming substrate spaced apart from the electron emission substrate. The image forming substrate includes an effective region where electrons emitted from the electron emission device collide with the effective region to form images and a black region surrounding the effective region. The effective region includes a fluorescent layer formed in an arbitrary pattern and a metal layer formed on the fluorescent layer. The metal layer has a structure extending onto at least a portion of the black region.

An improvement is made in a color picture tube having a substantially rectangular slit-aperture type shadow mask mounted therein in spaced relation to a substantially rectangular cathodoluminescent line screen. In the specific improvement, the cathodoluminescent lines of said screen, in front plan view, first increase in curvature with an increase in distance from the minor axis of the screen and then decrease in curvature with further increase in distance from the minor axis, to become substantially straight at the short sides of the screen.

A fluorescent screen including a plurality of parallel stripes of three colour phosphors is prepared by projecting light from a linear light source positioned in parallel with the stripes on photosensitive substances coated on the inner surface of the panel through a plurality of stripe shaped perforations of a colour selecting member, each divided into a plurality of slit shaped sections by means of bridges. The linear light source is constituted by reciprocating a point light source in parallel with the stripe shaped perforations.

An image display apparatus includes a rear plate and a face plate. The face plate 11 includes light emitting members spaced from and facing the plurality of electron-emitting devices in an image display region and emitting light responsive to irradiation with electrons, anodes mounted on the light emitting members, partitioning members interposed between the mutually adjacent light emitting members and protruding further than the light emitting members toward the rear plate, first resistance members each located in a portion of the partitioning members and spaced from and facing rear plate and electrically connected to the anodes; and second resistance members each covering a first resistance member and having a volume resistivity larger than that of the first resistance members to expose the first resistance members in the image display, wherein the partitioning member has a groove formed in the portion of the partitioning member opposing the rear plate, and the second resistance member is formed in the groove.

A light-emitting device (52, 80, 110, 128, or 130) suitable for a flat-panel cathode-ray tube display contains a light-emissive region (66) formed over a plate (64). The light-emissive region contains a plurality of light-emissive particles (72). Part of the outer surface of each light-emissive particle is conformally covered with one or more coatings (74, 82, 84, 112, and 114). The coatings variously provide light-reflection, gettering, intensity-enhancement, and contrast-enhancement functions.
摘要:
A display unit for displaying two-dimensional images and pictures comprises a fluorescent layer which fluoresces when irradiated with ultraviolet light and an electric-field ultraviolet light generating device provided behind the fluorescent layer for selective irradiation of the fluorescent layer. The fluorescent layer comprises different types of fluorescent material which emit different colors. The electric-field ultraviolet light generating device comprises a positive electrode layer, a positive hole injection layer, a light emission layer, and a negative electrode layer, respectively.
