The LG Optimus L9's 4.7" qHD screen (960 x 540 pixels) uses IPS technology and provides better contrast and viewing angles than the standard LCDs. The display has a density 234 pixels per inch, and while that's far from a standard-setting number, images are pleasantly detailed and crisp.
As long as you don't stare from too closely even small fonts are sharp enough and there's no pixelation. The L9 cannot quite match the deep blacks of AMOLED and the resulting contrast, but it's doing quite well in its price range.

LG Optimus L9 screen under a microscope
The Optimus L9 could be well out of some people's comfort zone with that 4.7" display but LG did a splendid job of using the available space. The nicely shaped sides and back of the handset allow a comfortable grip - more so than the 4X HD. The textured back looks somewhat simple, though by no means cheap, but is more secure that the fancy glass finish of the Optimus G.
LG Optimus L9 handles reasonably well given its screen size
The L9 is well-built and quite good-looking, which should hardly be a surprise. The L-series is more about looks than specs (even though the L9 is trying to raise the bid with a qHD screen and a dual-core processor). LG must've recognized the need of a reasonably powered and attractive alternative that costs significantly less than flagships. On the outside, it seems they got it right with the Optimus L9.
