Provided is a semi-transmissive liquid crystal display device in which the occurrence of display defects due to unevenness in cell gaps is suppressed. The liquid crystal display device includes a first substrate, a second substrate, and a liquid crystal layer. Each pixel includes a reflective region and a transmissive region. The first substrate has a reflective layer, an interlayer insulating layer provided so as to cover the reflective layer, and a pixel electrode provided on the interlayer insulating layer in each pixel. The interlayer insulating layer has a recess defined by the bottom surface and the inclined side surface, and at least a portion of the recess is located within the transmissive region. The depth of the recess of the interlayer insulating layer is 0.5 [mu] m or more, and the inclination angle of the inclined side surface of the recess is 25 DEG or less. 本发明提供一种抑制因单元间隙不均而导致的显示不良的发生的半透射型的液晶显示装置。液晶显示装置具备第一基板、第二基板和液晶层。各像素包含反射区域和透射区域。第一基板具有反射层、以覆盖反射层的方式设置的层间绝缘层以及像素电极，像素电极在各像素中，设置在层间绝缘层上。层间绝缘层具有
