The Nexus 4 has some serious chops, display-wise. Its 4.7-inch IPS panel faces the world with a native resolution of 1,280 x 786. That calculates to 320 pixels-per-inch. Apple's 4-inch Retina display, also an IPS, puts out 1,136 x 640, which equals 326 ppi. Both probably display more pixels than the human eye can discern, but Google's screen is bigger. It's also covered with Gorilla Glass 2, as opposed to the oleophobic (fingerprint-resistant) coating that protects Apple's glass.
