TRANSISTOR A COUCHE MINCE ET DISPOSITIF D'AFFICHAGE A CRISTAUX LIQUIDES UTILISANT CE TRANSISTOR

摘要

A thin film transistor formed on an insulating substrate (8) comprises a source electrode (15) connected to a source region (10), a drain electrode (16) connected to a drain region (11) and a channel region 9 between the source region and the drain region. The channel region is substantially covered by an extension of the source electrode 15 or the drain electrode. Another thin film transistor disclosed has a transparent contact connected to the drain region and lying on an insulation layer. The transistors are used in a LCD matrix including, in each element thereof, a display electrode 210 connected to a polysilicon layer on the transistor at a connection 209. The transistor is also connected to a signal electrode 207 at a connection 208.
