'jemanden links liegen lassen' (to ignore someone) and 'ignorieren' both mean that you deliberately pay no attention to a person. 'ignorieren' is the normal and direct verb. You can ignore a person, a message, or even a problem. 'jemanden links liegen lassen' is an idiom and sounds more figurative. It fits especially when someone deliberately gets no attention or is excluded. So the difference is mainly the form: 'ignorieren' is general and more neutral, while 'links liegen lassen' is a fixed expression and feels somewhat stronger or more personal.
