A reflecting color liquid crystal display device including a liquid crystal layer between a pair of opposing liquid crystal orientation films; transparent electrodes provided at outer surfaces of the orientation films; an upper glass base, a phase difference plate, and a front polarizing plate, which are laminated successively on an outer surface of one of the transparent electrodes; and a reflecting color polarized light filter provided at an outer surface of the other of the transparent electrodes, either directly or through an overcoat layer, such that a face of a polarized light color filter portion is in correspondence with the other of the transparent electrodes. Also disclosed is a reflecting color polarized filter including a reflecting layer provided at one face of a glass base, and a polarized light color filter portion provided on the reflecting layer. The reflecting color liquid crystal display device has at least the first of the two following characteristics: (1) capability of displaying dark and vivid colors, and (2) capability of displaying multiple colors. The reflecting color polarized light filter can be used in the reflecting color liquid crystal display device having such a characteristic.

A connecting structure for connecting a liquid crystal display and a flexible flat cable by soldering electrode terminals formed over the lower glass substrate of the liquid crystal display and connecting electrodes formed over the surface of the free end of the flexible flat cable, and by solidifying the junction of the liquid crystal display and the flexible flat cable with a resin. Through holes are formed in the free end of the flexible flat cable between the connecting electrodes at an appropriate pitch so that the through holes extend lengthwise across the end of the lower glass substrate when the flexible flat cable is put in place on the lower glass substrate. A resin applied to the upper surface of the flexible flat cable spreads over the upper surface of the flexible flat cable near the upper glass substrate of the liquid crystal display and the end surface of the upper glass substrate, flows through the through holes to the backside of the flexible flat cable, and spreads over part of the lower surface of the flexible flat cable near the end of the lower glass substrate and over the end surface of the lower glass substrate. Thus, the resin can be spread over the upper and lower surfaces of the flexible flat cable and over the respective end surfaces of the upper and lower glass substrates through a single resin applying process.
