An LED lamp includes a socket and a shallow dish-shaped body detachably connected to the socket. The socket is electrically connected to an external power source. The body includes a rear cover, a transparent front cover, a lamp board, a number of LED light sources, a driving circuit board and a fixing member. The LED light sources are mounted on the lamp board facing the front cover, wherein the LED light sources are visible from an outside of the transparent front cover when they are lit. The driving circuit board is electrically connected to the socket and the lamp board, and is configured for driving the LED light sources to emit light beams. The fixing member is configured for fixing the rear cover, the driving circuit board and the lamp board together.

摘要:
A liquid crystal display (LCD) panel includes a liquid crystal (LC) layer interposed between top and bottom substrates. The LC layer includes a plurality of LC compounds and a stabilization-aligned polymer polymerized from a plurality of polymerizable monomers and formed on at least one surface of the top substrate or the bottom substrate. The plurality of LC compounds comprise first, second, and third LC compounds in which the third LC compound is selected from the group consisting of a compound 3A, a compound 3B, a compound 3C, and combinations thereof. As seen from the chemical formulae, the plurality of LC compounds have condensed rings so that sensitivity to light and heat is reduced and reliability of the LCD panel is improved.
