LIGHT EMITTING DEVICE AND LIQUID CRYSTAL DISPLAY WITH THE LIGHT EMITTING DEVICE AS BACK LIGHT UNIT

摘要

A light emitting device and a liquid crystal display including the same as a backlight unit are provided to suppress damage of internal structure within a vacuum vessel due to an arching effect by forming a third electrode for absorbing arching current. A vacuum vessel is formed with a first substrate(12), a second substrate(14), and a sealing member. A plurality of first electrodes(22) are formed in a cross direction on the first substrate. A plurality of second electrodes(26) are formed along a direction crossing the first electrodes on the first electrodes. An insulating layer is formed between the second electrodes. A plurality of electron emission units(28) are electrically connected to the first electrodes or the second electrodes. One or more third electrodes(34A) are formed at a constant position apart from the second electrodes on the insulating layer in order to absorb arching current. A light emitting unit is formed on the second substrate.
