  There has been a need for an overcoat film composition that functions as an overcoat film in terms of high transparency and flatness, and that also functions as an aligning film in terms of liquid crystal molecular alignment. There has also been a need to lower the cost of manufacturing a liquid crystal display element. There is provided an overcoat film composition comprising one or more compounds selected from the group of polyester-polyamic acids (A1) obtained using at least a polyhydric hydroxy compound (a1), a diamine (a2), and a compound having two or more acid anhydride groups (a3), and polyester-polyimides (A2) that are imidization products thereof, and a polyamic acid (B).
