A liquid crystal display (LCD) driver including a normal mode circuit, a test pattern generating circuit, a selection circuit, and a timing controller. The normal mode circuit generates a normal mode signal related to a normal image data writing operation of an LCD. The test pattern generating circuit generates a test mode signal related to a test image data writing operation of the LCD. The selection circuit selects one of the normal mode signal and the test mode signal. The timing controller includes a memory storing image data that constructs a normal image pattern or a test image pattern displayed on an LCD panel of the LCD in response to an output signal of the selection circuit.
