The invention discloses a liquid crystal instrument for an electric vehicle. Sealants are arranged at a plurality of positions for sealing. The sealant consists of the following components in parts by weight: 3-4 parts of bisphenol-F diglycidyl ether, 1-2 parts of ceramic ultrafine powder, 4-5 parts of polyether millable polyurethane, 3-4 parts of bamboo charcoal fiber, 2-3 parts of fumed silica, 1-2 parts of anti-aging agent TMQ, 3-4 parts of methyltrimethoxysilane, 23 parts of dimer acid modified epoxy resin and 1-2 parts of lignosulfonate. By adopting the liquid crystal instrument for the electric vehicle disclosed by the invention, long-term waterproofness and damp protection of a liquid crystal display control circuit board are ensured, the liquid crystal display control circuit board can work effectively for a long time, and repair and detachment of the whole liquid crystal instrument for the electric vehicle due to dampening of the liquid crystal display control circuit board are avoided. The sealant can withstand high temperature up to 70 DEG C, and can withstand low temperature up to 20 DEG C below zero.
