Abstract: The liquid crystal display device includes a liquid crystal panel including a display area for displaying images and a non-display area other than the display area, a rigid board configured to connect with an external signal source, and a flexible board. The liquid crystal panel and the flexible board are arranged in a first direction. A direction perpendicular to the first direction and along a plate surface of the liquid crystal panel is a second direction. The flexible board is larger in a dimension in the second direction than the rigid board, and includes an end portion including at least an outer portion located outside of the rigid board in the second direction, and a middle portion located about a middle of the flexible board with respect to the end portion in the second direction. The end portion is larger in dimension in the first direction than the middle portion.

Abstract: In a working vehicle, an exhaust gas aftertreatment device is provided in an engine compartment that is adjacent to a cooling fan through which cooling air is supplied to a heat exchanger. The exhaust gas aftertreatment device includes a selective catalytic reduction device in which ammonia obtained from a urea aqueous solution is used as a reduction-causing agent. A urea aqueous solution pipe through which the urea aqueous solution is supplied is laid to the selective catalytic reduction device through the engine compartment. In the engine compartment, a pipeline-forming member having pipelines in which the urea aqueous solution pipe is installed. The cooling air sucked by a cooling fan flows into the pipelines.
