LCD describes the screen used to navigate the menu, look at photos you've taken, and in non-SLR cameras it servers as a digital viewfinder. An SLR, Single Lens Reflex, camera is one that actually shows the exact image you'll see through the lens. It does this by flipping down a mirror in the way of the sensor that captures the photo. It is for this reason that nearly all digital SLR cameras cannot have a live preview function where it shows the image on the LCD (barring high end SLRs). SLRs are aimed at higher end customers, are more expensive and make use of a detachable lens. Their picture quality is nearly always better than non-SLR cameras.

You need a film camera, so look for a film SLR, and not a digital SLR. Most film cameras don't have LCD screens, so that might be where you're getting confused.
SLR is higher, professional quality.
