In a substrate of a liquid crystal display device which forms a bus line which three-dimensionally intersects scanning signal lines, video signal lines and an insulation layer thereon, the present invention facilitates repairs of short-circuiting between the respective signal lines and the bus line. A liquid crystal display device includes a liquid crystal panel which is constituted of a pair of substrates with liquid crystal sandwiched therebetween. Out of the pair of substrates, one substrate includes a bus line which is arranged outside a display region and is electrically connected to a first conductive layer arranged inside the display region, and a plurality of signal lines which three-dimensionally intersect the bus line by way of an insulation layer. The bus line includes opening portions outside intersecting regions where the bus line is overlapped to the signal lines as viewed in a plan view. The opening portions are arranged on both sides of each intersecting region.
