user permission to see part on contacts

user permission to see part on contacts

I have grouped my contacts by creating views: Group1, Group2 and Group3 in 'Accounts'. I would like my new user to only see the information in Group1 of 'Accounts' and not Groups 2 and 3. 

I have tried to change the User Permission settings, but seems like i can either let her have permission to see 'Accounts' or not give her permission to do so. But I want her to only see part of 'Accounts'. 

Someone please help me ~ thank you!
