Abstract

Abstract PURPOSE:To omit a printed wiring board and to decrease the number of components by forming terminals, which are tape carrier terminals of a row and a column driving circuit and connected mutually, separately at two places and connecting them to corresponding terminals of an adjacent tape carrier in overlapping relation. CONSTITUTION:The circuits 12A, 12B, and 15 which drive the segment electrodes X and common electrodes Y of a liquid crystal panel 11 are composed of plural tape carriers (TAB) 13 and 16 by mounting LSI chips on respective plastic films, and the adjacent TABs 13 and 16 are arrayed having their side piece parts in overlapping relation. Respective output terminals of one LSI are provided on the narrow width part 19a of a plastic film 19 in an inverted T shape and input terminals are provided on the wide width part 19b separately at two places; and they are connected to same-function terminals of the adjacent TAB through a slit 20 in overlapping relation to omit the printed wiring board and decrease the number of components.
