Can anyone tell me how to make this code work?

I am trying to hide a div from within this code before I have it fade in,

Code:
<script type="text/javascript">
    $(document).ready(function(){
    $('#column-left').display="none";
    $('#column-left').fadeIn(2000);
    $('#column-middle').fadeIn(4000);
    $('#column-right').fadeIn(6000);
});
</script>
