Abstract: In a high-resolution liquid crystal display device, measures against display unevenness caused by generation of a region where no alignment film is applied are provided. A liquid crystal display device includes a pixel formed between a scanning line and a video signal line. The pixel includes a TFT, a pixel electrode, and a contact hole connecting the TFT and the pixel electrode. The contact hole is formed in an insulation film formed between the pixel electrode and the TFT. Assuming that a horizontal pitch of the video signal line is ph and a horizontal diameter of the contact hole is dh, ph is 26 μm or less and s/ph is 0.73 or more where s=ph−dh. A tapered angle of a sidewall of the contact hole is 53 degrees or less. A thickness of an alignment film over the pixel electrode is 110 nm or more.
