On the one hand, leaving it open makes your whole desk ready for action. You can sit down at a moment's notice to check breaking news or search for the latest cat video on YouTube. It's a welcoming position. And if you own a MacBook, it keeps the Apple logo upright. Because, yes, it matters to some of us.
On the other hand, a closed laptop takes up less space in your sight. It makes the desk look tidy. If your desk is positioned to face the room, a closed laptop keeps from visually breaking up the space. If your desk faces a wall, the closed laptop reveals the wall and decor behind it. The print on the wall or your inspiration corkboard are bared in all of their glory.
