A cooling fan assembly for cooling a heat exchanger includes a shroud having a plurality of stators extending radially to support a hub. The thin film transistor includes a source electrode, a drain electrode, a semiconducting layer, a transition layer, an insulating layer and a gate electrode. This results in combining structural insulated panel technology with insulated concrete form technology. Especially, in an attached state, an intersection angle \u03b1 formed between the backside seal slip and each of the leading lips is set to be smaller than an angle \u03b2 formed between the extending direction of the backside seal lip, and a vertical line. An electromotive force generated by electromagnetic induction is rectified and shaped by using primary coils formed on a check substrate and secondary coils formed on an array substrate, whereby a power source voltage and a driving signal are supplied to circuits or circuit elements on a TFT substrate so as to be driven.
