Abstract: A high-definition and high-contrast liquid crystal display device having a high aperture ratio without light leakage around a columnar spacer is provided. The liquid crystal display device of a horizontal electric field type includes a TFT substrate with a pixel electrode and a common electrode, a color filter substrate with a color filter, a columnar spacer interposed between the substrates, and a liquid crystal layer arranged between the substrates. A liquid crystal alignment film formed between the substrates is a photo-alignment film. The columnar spacer, formed on the color filter substrate or the TFT substrate, has a wall-like shape and an inclined surface extending in a direction parallel to or perpendicular to a direction in which the liquid crystal is initially aligned.
