A liquid crystal display panel includes a color filter array substrate having a first column spacer and a second column spacer, the first column spacer being partially inserted in a first hole, and a thin film transistor array substrate facing the color filter array substrate having a protective passivation film. The input device includes an input section for receiving inputs by hand and voice operations, a traveling state determination section for determining a traveling state of the mobile body, and an item executability determination section for determining, in the determined traveling state, whether each of the received inputs corresponds to an item executable by the hand and voice operations. %, \u2014a SU2+U3 content <40 wt. The regression-type angle detecting unit 904 statistically detects and outputs the angle as continuity in a regression equation. The fins are attached to the tube or post by press fitting, furnace or torch brazing, welding, or other method of mechanical bonding.
