How is Lady Macbeth presented in Shakespeare's Macbeth?

Whilst Shakespeare's 'Macbeth' may indicate that it is Macbeth himself that is the central protagonist, Lady Macbeth is instead the one who captures the audience's attention. This is because Lady Macbeth defies the conventions of her time; outspoken and incredibly influential, Lady Macbeth challenges the conventions of what it means to be a 'Shakespearian woman'. Indeed, this is most explicitly encapsulated in her demand to the gods, "unsex me here", insinuating that her gender would preclude her from committing the devious and harsh actions that she had in mind.
