Abstract: A liquid crystal display device includes a first substrate on which a thin film transistor is formed. The liquid crystal display device includes a first transistor which has a gate electrode thereof formed on a side more remote from the first substrate than a semiconductor layer and has a drain electrode thereof connected to the drain line, a second transistor which is connected to the first transistor in series, and has a source electrode thereof electrically connected to a pixel electrode, and a light blocking layer which is formed between the semiconductor layer and the first substrate and blocks a backlight incident from a first substrate side. The light blocking layer is formed in an overlapping manner on the first transistor, blocks a backlight incident on a first transistor side, and allows a backlight incident on a second transistor side to pass therethrough.
