The invention prevents a connection failure arising from an ingress of a conductive material, such as a solder ball, into a cholesteric liquid crystal layer in a liquid crystal display device having the cholesteric liquid crystal layer on a substrate when an electronic component is mounted to be connected to a conductor arranged on the substrate having the cholesteric liquid crystal layer thereon. A liquid crystal display device includes a liquid crystal cell having a liquid crystal layer between an upper substrate and a lower substrate bonded to each other with a sealing member interposed therebetween. First conductors are arranged on the inner surface of the lower substrate and second conductors are arranged on the inner surface of the upper substrate. A transflective layer containing a cholesteric liquid crystal layer is arranged between the lower substrate and the first conductors. Electronic components are mounted on the inner surface of the upper substrate outside the sealing member. The electronic components are electrically connected to the second conductors and are electrically connected to the first conductors through inter-substrate conductors.
