Abstract
【解決手段】 リアフレーム41上に反射シートを介してモールドフレーム43が取付けられ、モールドフレーム43の枠内でLED光源44と導光板46の一端面とが近接又は密接して対置される。
モールドフレーム43のLED光源44と導光板46の一端面が近接又は密接して対置される側の反対側は、導光板46をLED光源44に押し付けるための弾性手段43cと導光板の位置決め手段43dが設けられており、LED光源44と導光板46の一端面が近接又は密接して対置される側においては導光板46の一端がLEDを取付けたフレキシブルプリント基板44aの下に潜り込むようにする。

Claims (5)
- リアフレーム上に反射シートを介してモールドフレームが取付けられ、該モールドフレームの枠内に発光ダイオード光源と導光板の一端面とが近接又は密接して対置される液晶表示装置において、前記モールドフレームは、発光ダイオード光源と導光板の一端面が近接又は密接して対置される側とは反対側に導光板を発光ダイオード光源に押し付ける弾性手段及び導光板の位置決め手段を備えており、発光ダイオード光源と導光板の一端面が近接又は密接して対置される側の導光板の一端がダイオードを取付けたフレキシブルプリント基板の下に潜り込むようになされていることを特徴とする液晶表示装置。
- 前記弾性手段が前記モールドフレームの一辺の中央部分と前記リアフレーム間に隙間を備え、該モールドフレーム内方向への押圧力を生じるものであることを特徴とする請求項1に記載の液晶表示装置。
- 前記位置決め手段が前記モールドフレームに設けた凹所とこれに対応して前記導光板に設けた突起であることを特徴とする請求項1に記載の液晶表示装置。
- 前記フレキシブルプリント基板の幅方向端面から所定寸法後退した位置で前記発光ダイオードの発光面が導光板端面に対置されるようフレキシブルプリント基板に発光ダイオードを取付けたことを特徴とする請求項1に記載の液晶表示装置。
- 前記フレキシブルプリント基板は、該フレキシブルプリント基板に取付けた複数の発光ダイオードの間並びに該フレキシブルプリント基板の両端にそれぞれ施した両面接着剤により前記モールドフレームに固定されていることを特徴とする請求項4に記載の液晶表示装置。
