SSL certificate by Comodo. What to do?

I just got a free SSL certificate from Comodo SRL. I generated the private key and the CSR from the cpanel, then i proceeded with the thing on Comodo and added the certificate. If i access the site via https, it says the certificate is not secure.
Did i do anything wrong or i just need to wait?

The certificate looks secure from my end. Wait some time for your browser to recognize it.
