Should i pursue computer science, or software engineering?

i'm considering pursuing an undergraduate degree in computer science, but i'm also thinking perhaps software engineering could be more appropriate for me. can someone explain the real difference?

for some background: i'm a b-sch graduate who considers myself a tech entrepreneur as well. i'm fascinated by the idea of "software eating the world" and i believe i have very good ideas that if executed well, can become viable businesses and even disrupt industries. i don't see myself being a software engineer or a computer scientist, but the purpose of my pursuing a second undergrad degree in this field is because i want to have a technical understanding of my business, i.e i want to be a technical founder. i am particularly interested in developing web-based products, or consumer-facing products delivered through the internet.

which is the route i should choose?
