Patent ID: 8373824

Claim:
A liquid crystal display device, comprising: a liquid crystal display panel including a plurality of sandwich substrates for sandwiching liquid crystal there between; and a backlight unit which is covered with the liquid crystal display panel, the backlight unit including a light guide plate for applying light with respect to the liquid crystal display panel, wherein, in the liquid crystal display panel, when a sandwich substrate nearest to the light guide plate is defined as a first sandwich substrate, and, out of substrate surfaces of the first sandwich substrate, a substrate surface facing the light guide plate is defined as an outer substrate surface, a light source for supplying the light to the light guide plate is attached to the first sandwich substrate and a light emitting surface of the light source is positioned on the outer substrate surface side; wherein the light source is mounted on the outer substrate surface of the first sandwich substrate; and wherein: on the outer substrate surface, an electrode of the light source is positioned; on a sandwich substrate surface which is a substrate surface on a rear side of the outer substrate surface, a panel wiring through which a current is allowed to flow is mounted; and in the first sandwich substrate, a through hole for causing the panel wiring to extend from the sandwich substrate surface to the outer substrate surface is formed.
