Abstract: According to an aspect, a display device includes: a display panel including an array substrate, a counter substrate, a liquid crystal layer between the array substrate and the counter substrate, and spacers projecting from the counter substrate toward the array substrate; a light-transmitting glass base member bonded to the display panel; and a light source that includes a light guide provided along a side surface of the array substrate, a side surface of the counter substrate, or a side surface of the glass base member, and light emitters facing the light guide. The array substrate includes: signal lines; scan lines; and switching elements coupled to the scan lines and the signal lines. The spacers are arranged in positions facing the respective switching elements and are provided with adhesion layers provided such that the counter substrate and the array substrate adhere to each other.

Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, a sealant formed bonding the first substrate with the second substrate, a liquid crystal layer surrounded by the sealant, and a light emitting module. The sealant includes a first portion, a second portion opposed to the first portion with the liquid crystal layer sandwiched therebetween, an inlet formed in the second portion, and a filling material filled in the inlet. The liquid crystal layer is arranged over a display area where an image is displayed, a first area between the display area and the first portion, and a second area between the display area and the second portion, in plan view. A first width of the first area is larger than a width of the second area.

Abstract: A display device includes a display region, a peripheral region around the display region, a sealing portion provided in the peripheral region to seal a liquid crystal layer, and a liquid crystal supply portion provided at a part of the sealing portion and interconnecting an outside of the sealing portion and the display region. The peripheral region includes a first peripheral region which is provided between the display region and the sealing portion and from which an insulating film is removed and a second peripheral region which is provided between the display region and the sealing portion and in which the insulating film covering a circuit is formed. A light blocking film arranged so as to straddle the first and second peripheral regions and extending linearly in an extending direction of a boundary between the first and second peripheral regions is formed on a substrate.

Abstract: A display device includes: an array substrate; a counter substrate; a liquid crystal layer between the array substrate and the counter substrate; and a light source disposed so as to emit light into a side surface of the array substrate or a side surface of the counter substrate. The array substrate includes: signal lines arranged in a first direction with spaces interposed between the signal lines; scan lines arranged in a second direction with spaces interposed therebetween; a switching element coupled to a corresponding one of the scan lines and a corresponding one of the signal lines; an organic insulating layer that covers at least the switching element; and a metal layer provided on the upper side of the organic insulating layer so as to overlap the organic insulating layer. A positional misalignment portion of each signal line does not overlap a positional misalignment portion of the metal layer.
