Abstract: A method of manufacturing a panel assembly used to assemble a display panel intends to achieve an alignment-free between barrier ribs and a fluorescent layer and minimize the waste of a barrier rib material for cost reduction. On a support body 51 which is not a substrate, formed are a plurality of walls 281 through 283 made of a fluorescent material that are belt-shaped in plan view arranged in stripes, an electrode material layer a1, and a barrier rib material filling spaces between the walls. The support body 51 and a substrate 21 are coupled so that the barrier rib material faces the substrate. The walls 281 through 283, the electrode material layer a1 and the barrier rib material 291 are transferred in one step to the substrate 21, and thus a panel assembly 20 having barrier ribs 29, electrodes A and fluorescent layers 28R, 28G and 28B is obtained.

Abstract: A backlight device for a transmissive liquid crystal display device includes a plurality of light sources, including a cold cathode fluorescent lamp and an LED, a liquid crystal panel, and a light guide plate. The light guide plate causes light entering into it through one surface thereof to emerge out of another surface thereof toward the liquid crystal panel. A controller for the backlight device selects at least one of the cold cathode fluorescent lamp and LED, depending on brightness required for the liquid crystal display device and determines, in accordance with the required brightness, the brightness of the selected light source to operate the light source accordingly.

Abstract: In a liquid crystal display device that uses a liquid crystal material having spontaneous polarization and is actively driven by a TFT, a voltage corresponding to image data is applied twice by driving the TFT of each pixel electrode on a line by line basis of a liquid crystal panel, during writing in one frame. During erasure in one frame, voltage application to liquid crystal by batch selection of all the pixel electrodes is performed three times. With this three times of voltage application, it is possible to achieve a black display state in each pixel and make the stored charge amount at the liquid crystal in each pixel substantially zero.

Abstract: Local losses of material of transparent electrodes, in a plasma display panel including transparent electrodes, bus electrodes and, a dielectric layer covering these electrodes, are prevented by using a plasma display panel according to the present invention. The plasma display panel is formed on at least one substrate of a pair of substrates provided opposite each other via a discharge space. An element, which is a main element of the bus electrode composition, is included in the composition of the dielectric layer. Since the main element of the bus electrode is included in the dielectric layer, local losses of the transparent electrode can be prevented even through the high temperature baking process of the dielectric layer. A preferred choice as the main element of the bus electrode composition is copper, but other elements are also suitable and will perform acceptably.

Abstract: A plasma display panel has a first substrate, a plurality of address electrodes disposed on the first substrate, a first dielectric layer disposed on the first substrate in covering relation to the address electrodes, a second substrate, a plurality of scan electrodes disposed on the second substrate in a direction transverse to the address electrodes, a second dielectric layer disposed on the second substrate in covering relation to the scan electrodes. The first substrate and the second substrate are disposed in confronting relation to each other with discharge spaces defined therebetween. The first dielectric layer contains electrically conductive particles mixed therewith. The electrically conductive particles make the first dielectric layer electrically conductive in its transverse direction to allow charges stored on the first dielectric layer to leak to the address electrodes for thereby reducing the frequency of random discharges.
