PURPOSE: A liquid crystal display device is provided to make irregular luminance, which occurs in portions of a displayed image coincident with borders among blocks, indiscernible. CONSTITUTION: The liquid crystal display is different from the prior art that a first sample-and-hold circuit(310), a correction circuit(311), an addition circuit(312), and a second sample-and-hold circuit(313) are included in an image processing circuit(300A) to overcome the irregular luminance. The first sample-and-hold circuit(310) samples and holds an input image signal(VID) during a period during which a sample-and-hold signal(SHl) remains high, and produces an image signal(VIDa1). The sample-and-hold signal(SH1) is produced for each block, and goes high during one sampling period immediately after handling a block is started.
