Abstract: In the present embodiment, a sealing agent (50) sealing two substates contains a low melting-point glass material and is adhered to each of a first substrate (10) and a second substrate (20), a barrier rib (60), which is formed in such a manner as to surround the outer periphery of an electronic element (30), is disposed between the sealing agent (50) and the electronic element (30), and between the first substrate (10) and the second substrate (20), and the sealing agent (50) is spaced apart from the barrier rib (60). As a result, a deterioration of the electronic element, caused by the heat produced when sealing, may be prevented while the electronic element formed between the two substrates is protected from moisture and oxygen.

The liquid crystal module includes: a liquid crystal panel including a first polarizer, a first substrate, a liquid crystal layer, an in-cell retardation layer (λ/4 plate of nx>ny=nz), a second substrate, an out-cell retardation layer (λ/4 plate of nx>ny≥nz), and a second polarizer, from a back side toward an observation side; and a backlight. The backlight includes a first prism sheet including a first ridge line, and a second prism sheet provided on a back side from the first prism sheet and including a second ridge line orthogonal to the first ridge line. The first ridge line is parallel to an azimuth at which the liquid crystal panel has a maximized transmittance in an oblique direction during black display.
