A display is provided which is easy in the fabrication, highly resistive to heat and ultraviolet ray, and suited for a large-screen. The magnetic fluid display comprises a magnetic fluid display board (1) having a magnetic fluid (4) which contains magnetic particles (4A) dispersed uniformly and suspended constantly and is filled in a space provided between two equally spaced transparent panels (2), and an image display controlling means (5) for generating selectively in response to the data of an image signal a matrix of magnetic fields towards pixel areas on and across the thickness of the magnetic fluid display board. When the magnetic fluid in the magnetic fluid display board is activated by a desired number of the magnetic fields determined by the image signal, its magnetic particles are controlled in the orientation. Accordingly, a combination of resultant light passing and light blocking areas of the pixels will is created in the magnetic fluid forming an image. <IMAGE> |
