    Abstract: An electron source emits electrons as a function of input signals. The electron source comprises a substrate (1), a matrix of wires having m row wires and n column wires laid on the substrate with an insulator layer interposed therebetween, and a plurality of surface-conduction electron-emitting devices each having a pair of electrodes (5,6) and a thin film (4) including an electron emitting region (3) and arranged between the electrodes. The electron-emitting devices are so arranged as to form a matrix with the electrodes connected to the respective row and column wires. Each pixel unit is irradiated by at least two electron beams emitted from the respective electron emitting regions which are juxtaposed with interleaving the higher potential device electrode therebetween and a gap interval W in the juxtaposing direction of which satisfies equation (1) below: K2 x 2H(Vf/Va) ≥ W/2 ≥ K3 x 2H(Vf/Va) where K2 = 1.25 +/- 5.05, K3 = 0.35 +/- 0.05, H is the distance between the surface-conduction electron-emitting devices and the image-forming member, Vf is the voltage applied to the surface-conduction electron-emitting device and Va is the voltage applied to the image-forming member.

    Abstract: A method of forming a semiconductor thin film based on crystallizing a thin film crystal from an amorphous thin film by solid phase growth. A plurality of small regions which are preferentially made nuclei generation points are formed at predetermined positions in the amorphous thin film. Solid phase growth from single nuclei formed in the small regions is preferentially effected by heating to form a crystalline semiconductor thin film in which the grain boundary positions are adjusted to the desired positions. This crystalline semiconductor thin film is subjected to a heat treatment to reduce defects in crystal grains.

    Abstract: A display apparatus, comprises a plurality of pixels arranged in pluralities of rows and columns a plurality of first control lines each connecting a column of pixels in common, and a plurality of second control lines each connecting a row of pixels in common. The first control lines are divided into a plurality of blocks. Third control lines are disposed so that the first control lines in each of the blocks are commonly connected by a third control line. A multiplexing switching element is disposed at each connection between the third control lines and the first control lines. Further, a difference in output voltage between two multiplexing switching elements disposed at a boundary between a neighboring pair of blocks is 50 mV or less.
