I am using Qt4 to build an application and for some reason I want to keep it proprietary. Qt4 is released under LGPL, does that force me to release the code to my application. I ask this question because I am finding it difficult to understand the LGPL license.

Yes.

"The main difference between the GPL and the LGPL is that the latter allows the work to be linked with (in the case of a library, 'used by') a non-(L)GPLed program, regardless of whether it is free software or proprietary software.

In addition to @user64152's answer I have to add one more thing. If along with proprietary you also intend to make a commercial product and modify the Qt libraries, you have to buy the Qt Commercial License in order to be able to sell your product.
