Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a high quality color filter in which a colored layer is formed even on a light-shielding layer without impairing flatness in the method of manufacturing a color filter (a pointing BM method). SOLUTION: When a colored layer of a color filter consisting of a prescribed pattern colored layer and light-shielding layer on a transparent substrate having a conductive layer, is formed by an electro-deposition method, the light-shielding layer pattern is formed on the transparent substrate beforehand by using a light-shielding material before the colored layer is formed, a baking temperature is lowered or a baking time is shortened so that an electro-deposition resistance per a unit cm<2> of the light-shielding layer becomes not lower than 10<5> Ω and a current value at the time of measuring the resistance becomes not exceeding 1 mA. Further, when the coloring layer is formed by electro-deposition method, it is prevented that the coloring layer is formed on the light-shielding layer superimposed, by increasing the light-shielding layer in the thickness.

Title: Power supply device for picture display device
Inventor: KANAI TOSHIO
IPC: H02M3/28
Filed: 1990-03-28
Abstract: PURPOSE:To protect a deflection circuit and to facilitate the discrimination of a fault location of an oscillation circuit by controlling an output from a DC voltage conversion means so as to be decreased when the oscillation circuit is stopped. CONSTITUTION:When an oscillation circuit 16 of a DC voltage conversion sec tion stops the operation, a transistor(TR) 36 is interrupted. Thus, since an emit ter current of a TR 34 flows to a resistor 35, the emitter current is limited, the collector current of a TR 33 is less than a regular value and power fed to a deflection circuit 41 is reduced. Thus, a voltage applied to the deflection circuit 41 is reduced when the operation of the oscillation circuit 16 is stopped to protect the deflection circuit 41 and an output of the DC voltage conversion section is not stopped, resulting in facilitating fault diagnosis.
