Abstract:
It is not appropriate to use such a brittle material as glass and such a metallic material, which is heavy and inferior in flexibility, as stainless steel in order to supply consumers with display devices convenient to deal with. It is possible to solve the above problem by the present invention. The purpose of the present invention is to supply display devices which are excellent in productivity, light in weight and flexible. In order to solve the above problems, a constitution of the display device of the invention is shown in the following. The display device includes a pixel unit including TFTs of which the active layer is made of an organic semiconductor material for forming channel portions in the opening portions in an insulating layer arranged to meet the gate electrodes. The pixel unit further includes a contrast media formed on the electrodes connected to the TFTs for changing the reflectivity upon the application of an electric field, or microcapsules containing electrically charged particles that change the reflectivity upon the application of an electric field. The pixel unit is sandwiched by plastic substrates, and barrier layers including an inorganic insulating material are provided between the plastic substrates and the pixel unit.

Disclosed is a cold cathode type fluorescent lamp operated with a low voltage while it has a greatly increased life. The cold cathode type fluorescent lamp has a fluorescent tube including a fluorescent material formed thereon. A discharge gas includes vapors of mercury and an inert gas by a ratio of approximately 1:0.6 to 1:2.0. A first base and a second base are installed at both end portions of the fluorescent tube. A first electrode is disposed in the fluorescent tube, and a second electrode is disposed in the fluorescent tube. A first electron-emitting member is fixed on the first electrode, and a second electron-emitting member is fixed on the second electrode. The cold cathode type fluorescent lamp can instantaneously operate without preheating the electrodes, and cold cathode type fluorescent lamp can have greatly increased life because the cold cathode type fluorescent lamp can continuously operate when the electron-emitting members are broken. Also, the cold cathode type fluorescent lamp can be employed for various purposes like a traffic lamp or a street lamp because the cold cathode type fluorescent lamp has the sufficient luminous intensity.

An image-forming apparatus comprises an envelope, an electron source and an image-forming member arranged within the envelope, as well as an electron source drive circuit. An electroconductive member is arranged on the inner wall surface of the envelope between the electron source and the image-forming member. An electric current flow path A is formed as extending between the electroconductive member and the ground without passing through any of the electron source and the drive circuit. The electric current flow path A has a resistance lower than the resistance of another electric current flow path B extending between the electroconductive member and the ground by way of the electron source or the drive circuit.
