NOVELTY - A field-effect transistor comprises a transparent conductive film (2), which is formed together with a picture element electrode, a metal film (3), which is formed together with a signal wiring, a multi-layer film, and an insulation substrate (1). The multi-layer film consists of a semiconductor film (4), a gate insulation film (5), and a gate metal film (6).    USE - For active matrix liquid crystal displays.    ADVANTAGE - The field-effect transistor has enhanced ohmic characteristics and realizes a liquid crystal display equipment with high aperture efficiency and low resistance signal wirings. It has low leakage current between the source and drain when the gate of the transistor is negatively biased.    DETAILED DESCRIPTION - A field-effect transistor comprises five regions and a current flow path generated through the fifth region between the first and second regions when a predetermined voltage is applied to the third region. The first and the second region is made of transparent and opaque conductive material respectively. These two regions are physically and electrically connected to the fifth region. The third region is made of conductive material and is deposited on the fourth region, which is made of insulation material and is deposited on the fifth region. The fifth region is made of a semiconductor material. INDEPENDENT CLAIMS are also included for (a) a fabrication of the field-effect transistor comprising forming a metal film on an insulation substrate. The metal film is patterned into a first and second metal electrodes. An impurity gas is discharged over the two electrodes. An amorphous silicon film, an insulation film, and a gate electrode film are deposited, in sequence, on the first and second electrodes. A multi-layer film is patterned into a gate electrode pattern; and (b) an image display apparatus comprising the field-effect transistors.
