Abstract: A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal sandwiched between the substrates, and a display region. A hole portion is formed in the display region. A first seal portion is formed to surround the display region. A second seal portion is formed to surround the hole portion. The first and the second seal portions seal the liquid crystal. The second seal portion has a first end portion on the liquid crystal side and a second end portion on the opposite side of the liquid crystal side. A sealing material is present in the first end portion. A sealing material is present in the second end portion. A wall-like spacer is formed between the first and the second end portions to surround the hole portion. The wall-like spacer defines the gap between the first and the second substrates.
